First Workshop on Approaches to Mining Mass Opinion for Business Intelligence (AMMBI)

First Workshop on Approaches to Mining Mass Opinion for Business Intelligence (AMMBI)
(Held in conjunction with ICAI 2010 - Las Vegas, Nevada, USA)

Mass opinion mining is related both to subjectivity and sentiment analysis, two tasks of growing importance in the field of Natural Language Processing (NLP), as well as other disciplines such as economics, psychology and sociology. Although studied separately, the task can benefit from an interdisciplinary approach, due to its difficulty and the multitude of facets that it contains.

The aim of this workshop is to bring together researchers in computational linguistics, dealing with subjectivity and sentiment analysis, but also from other disciplines related to the task of mass opinion mining and/or estimation: psychologists, sociologists, economists etc., with the objective of facilitating an interdisciplinary dialogue on the analysis, requirements, issues and applications of the study and modelling of mass opinion.

Topics of interest

We welcome original and unpublished evaluation or position papers on all (mass) opinion mining issues. Some suggested topics include, but are not limited to:

• Mass opinion estimation based on NLP and statistical models
• Opinion mining and behavioural studies in the context of social networks
• Opinion retrieval, extraction, categorization, aggregation and summarization
• Information bias and perspective determination for source trust and reputation determination
• Computational analysis of persuasion techniques
• Correlation of factual and opinionated data based on socio-economic models
• User profile definition for personalized retrieval
• Topic relevance analysis for information monitoring
• Topic and sentiment studies and applications of topic-sentiment analysis
• Use of Semantic Web technologies for factual and subjective data analysis
• Proposals involving the computational treatment of large amounts of subjective data
• Applications of opinion mining systems to real-world business scenarios

Important Dates

• Paper submission deadline: March 10, 2010

CGFP: TIR'10 - 7th International Workshop on Text-Based Information Retrieval

TIR'10 - 7th International Workshop on Text-Based Information Retrieval
In conjunction with the DEXA 2010: 21st International Conference on Database and Expert Systems Applications
Bilbao, Spain, August 30 - September 3

Intelligent algorithms for mining and retrieval are the key technology to cope with the information need challenges in our media-centered society. Methods for text-based information retrieval receive special attention, which results from the important role of written text, from the high availability of the Internet, and from the enormous importance of Web communities.

Advanced information retrieval and extraction uses methods from different areas: machine learning, computer linguistics and psychology, user interaction and modeling, information visualization, Web engineering, artificial intelligence, or distributed systems. The development of intelligent retrieval tools requires the understanding and combination of the achievements in these areas, and in this sense the workshop provides a common platform for presenting and discussing new solutions.

The following list organizes classic and ongoing topics from the field of text-based IR for which contributions are welcome:

• Theory. Retrieval models, language models, similarity measures, formal analysis
• Mining and Classification. Category formation, clustering, entity resolution, document classification, learning methods for ranking
• Web. Community mining, social network analysis, structured retrieval from XML documents
• NLP. Text summarization, keyword extraction, topic identification
• User Interface. Paradigms and algorithms for information visualization, personalization, privacy issue
• User Context. Context models for IR, context analysis from user behaviour and from social networks
• Multilinguality. Cross-language retrieval, multilingual retrieval, machine translation for IR
• Evaluation. Corpus construction, experiment design, conception of user studies
• Semantic Web. Meta data analysis and tagging, knowledge extraction, inference, and maintenance
• Software Engineering. Frameworks and architectures for retrieval technology, distributed IR

The workshop is held for the seventh time. In the past, it was characterized by a stimulating atmosphere, and it attracted high quality contributions from all over the world. In particular, we encourage participants to present research prototypes and demonstration tools of their research ideas.

Important Dates:

• Mar 30, 2010 Deadline for paper submission

CFP: Workshop NeSp-NLP 2010: Negation and Speculation in Natural Language Processing

Workshop NeSp-NLP 2010: Negation and Speculation in Natural Language Processing
July 10, 2010, Uppsala, Sweden

In recent years, research has yielded substantial progress in NLP tasks like NE recognition, WSD, parsing, semantic role labeling, and anaphora resolution among others. This has been in part supported by the organisation of shared tasks, which provide annotated data, a definition of the task and an evaluation framework, motivating researchers to develop new techniques to tackle these tasks. Other tasks like paraphrasing, summarization or textual entailment have also progressed, but results are still relatively low because deep understanding of language - mapping meaning to meaning - is necessary. This raises methodological questions. Furthermore, large scale linguistic resources are still lacking.

Negation and speculation are two phenomena involved in deep understanding of text. Both are related to expressing the factuality of statements, that is, expressing to which extent a statement is or is not a fact or a speculation. Negation turns an affirmative statement into negative (it rains/it does not rain). Speculation is used to express to which extent a statement is certain or speculated (it might rain/apparently, it will rain/ it is likely to rain/it is not clear whether it will rain/we suspect that it will rain).

SCOPE AND TOPICS

In this workshop we aim at bringing together researchers working on negation and speculation from any area related to computational language learning and processing. The general goal of the workshop is to stimulate research about these topics. Specific goals are to describe the lexical aspects of negation and speculation, to define how the semantics of these phenomena can be modelled for computational purposes, to explore techniques aimed at learning the factuality of an statement, and to analyse how the treatment of these phenomena affects the efficiency of NLP applications. Finally, the workshop aims at encouraging discussion about the need of deep linguistic processing as a way to take computational linguistics a step further.

The wokshop will address the following aspects of negation and speculation, although it will be open to other related topics:

• Lexical aspects of negation and speculation
• Linguistic resources with information about negation and speculation: corpora, dictionaries, lexical databases
• Descriptive analysis of negation and speculation cues
• Negation and speculation across domains and genres
• Negation and speculation in biomedical texts and biomedical text mining
• Handling negation and speculation in NLP: dialogue systems, sentiment analysis, text mining, textual entailment, information extraction, machine translation, paraphrasing
• Learning the scope of negation and speculation cues
• Interaction of negation and speculation for evaluating the factuality of an statement
• Corpora annotation: guidelines, bootstrapping techniques, quality assessment
• Modelling factuality for computational purposes
• Algorithms to learn negation and speculation
• Structured prediction of negation and speculation
• Joint learning of negation and speculation
• Inference of factual knowledge

IMPORTANT DATES

• May 14 - Deadline for workshop papers
• June 15 - Notification of acceptance
• June 25 - Camera-ready papers due
• July 10 - Workshop in Uppsala

Music recommendation dataset by Oscar Celma & last.fm

Thanks to a FB comment by Jose Carlos, I have discovered this really interesting dataset. Oscar Celma, Ph.D, Chief Innovation Officer @ Barcelona Music & Audio Technologies, has written a very interesting thesis on Music Recommendation, with the plus of making his dataset available to the community.

This dataset contains tuples (for ~360,000 users) collected from Last.fm API, using the user.getTopArtists() method, and it is ~543Mb. The data is made available for non-commercial use. As it essentially features <user, artist, plays> tuples, it is very interesting for testing a number of collaborative recommendation techniques and functions (recommending music & artists). However, I miss it was date-tagged, in order to examin how a system would evolve regarding recommendations and feedback.

It contains 17,562,018 tuples, beware if you are going to use non-sparse representations.

RapidMiner video tutorials

RapidMiner (formerly YALE (Yet Another Learning Environment)) is an environment for machine learning and data mining experiments. It allows experiments to be made up of a large number of arbitrarily nestable operators, described in XML files which are created with RapidMiner's graphical user interface. RapidMiner is used for both research and real-world data mining tasks.

RapidMiner is a very good alternative to WEKA . I suggest to check the tutorials at the Rapid-I website:

• A quick tour video demonstrating some of the features of RapidMiner 5 within 3 minutes.
• RapidMiner Video Tutorial 1: User Interface and First Process (First Start and User Interface, Operators, First Process).
• RapidMiner Video Tutorial 2: Data Import and Repositories (Importing Data, Using Data in Processes, Meta Data).
• RapidMiner Video Tutorial 3: Modeling and Scoring (Basic Terms, Training a Data Mining Model, Applying Models for Scoring).
• RapidMiner Video Tutorial 4: Visualization (Visualizing Data, Visualizing Models and other Results, Result Overview).
• RapidMiner Video Tutorial 5: Evaluation and Performance Estimation (Nested Subprocesses, Evaluation by Cross Validation, Calculation and Visualization of Performances).
• RapidMiner Video Tutorial 6: Data Transformations (Basic Preprocessing Operators, Meta Data Transformation and Propagation, Quick Fixes).

CERI welcomes innovative contributions from a wide range of knowledge areas (not only Computer Science but also Information Science, Linguistics, etc.).

Furthermore, within this conference, the organizers aim at promoting the constitution of the Spanish Society of Information Retrieval. This new Society would support IR in Spain and it is the organizers' intention that the Society starts with as much support as possible. All scientists interested in the creation of this Society are welcome to participate.

We encourage national and international researchers to submit original papers, written in spanish or english, related to any aspect of IR including, but not limited to:

• IR models

CFP: Intelligent Methods for Protecting Privacy and Confidentiality in Data

Intelligent Methods for Protecting Privacy and Confidentiality in Data
May 30th, 2010, Ottawa, Canada

Submission deadline: March 30th

With the increasing adoption of electronic medical/health records and the rising use of electronic data capture tools in clinical research, large electronic repositories of personal health information (PHI) are being built up. At the same time, large medical data breaches are becoming common. Data breaches may be caused by errors committed by insiders at the data custodian sites, or by malicious insiders. Data
breaches can also be caused by outsiders breaking into the data repositories. These data breaches represent legal and financial liabilities for the data custodians, and erode public trust in the ability of data custodians to manage their PHI.

An area that has grown in importance to manage the risks from breaches is data leak prevention (DLP). DLP technologies monitor communications or networks to detect PHI leaks. When a leak is detected the affected individual or organization is notified, at which point they can take remedial action. DLP can prevent a PHI leak or detect it after it happens. For example, if DLP is deployed to monitor email then a PHI alert can be generated before the email is sent. If DLP is used to monitor PHI leaks on the Internet (e.g., on peer-to-peer file sharing networks or on web sites), then the alerts pertain to leaks that have already occured, at which point the affected individual or data custodian can attempt to contain the damage and stop further leaks.

Computational AI is a key enabling technology for next-generation DLP technologies. This workshop aims to bring together researchers working on computational tools for DLP.

Topics of interest include, but are not limited to:

• reviews: reviews of DLP systems and methods; and reviews of PHI leaks that are occuring.
• methods: detection of personally identifying information in text; detection of health information in different types of text (e.g., professionally written vs. lay person generated); and re- identification risk assessment;
• applications: monitoring the web and peer-to-peer file sharing networks for PHI leaks; detection of PHI in email or other communications; and tools for dealing with PHI leaks in an automated way (e.g., de-identification).
• evaluation: empirical evaluation of deployed systems; theoretical methods of risk assessment; and new methods for evaluating such systems.

Workshop Format

The workshop invites position papers describing original work in theory and applications of intelligent methods to the problem of DLP. Position papers will be reviewed by the Program Committee members according to their originality, technical merit and clarity of presentation. Each accepted paper will be allocated a maximum of 5 pages in the workshop proceedings. At least one author for each accepted paper is expected to attend the workshop.

The workshop is planned to be interactive with discussions on the current state and future developments in the area of DLP for PHI. All of the workshop attendees will co-author a final report on DLP for PHI after the workshop and submit that to a journal.

Location

The workshop is being held in conjunction with the Canadian AI 2010 conference.

Open Competition: ECML/PKDD 2010 Discovery Challenge

The focus of the ECML/PKDD 2010 Discovery Challenge is Web Content Quality.

High quality is not simply the opposite of Web Spam. The recent Web Spam Challenges have explored the aspects of filtering as a binary decision. In this year's Discovery Challenge we target at more and different aspects. We want to develop site-level classification for the genre of the web sites (editorial, news, commercial, educational, "deep Web", or Web spam and more) as well as their readability, authoritativeness, trustworthiness and neutrality.

The data set will consist of sample Web hosts from Europe in three languages (English, French and German). The training and testing samples will be biased towards the interesting aspects and cleansed manually from mixed sites, Web hosting, and adult content. Features similar to those used to filter Web spam based on content and linkage information will be provided on the host level, along with natural language processing annotations of a large set of sample pages.

Preliminary description of tasks.

1. Classification task

A ranked list is required for the English documents for all categories (news, educational, spam; readability, authority, neutrality). Evaluation is in terms of average NDCG.

2. Quality task

Quality is measured as an aggregate function of all content type and quality. A single ranked list is required and is evaluated in terms of NDCG.

3. Multilingual quality task

Quality predictions for the non-English language sites is required as in Task 2. Evaluation is is in terms of average NDCG.

Important dates (tentative).

• Mid-February : description of the content types (news, educational, spam etc) and properties (readability, authoritativity, Neutrality) along with the assessor guidelines are out.
• Mid-March : Data set and training labels are out.

The ACM Hypertext Conference is the main venue for high quality peer-reviewed, double-blind research on "linking" and interconnectivity. The Web, the Semantic Web, Web 2.0 and Social Networks are all manifestations of the success of the link concept.

Technical Tracks:

Hypertext 2010 will consist of three autonomous tracks, each with its own Track Program Committee. These Tracks are intended to represent the spectrum of Hypertext. If you cannot figure out where you fit, submit to the best fitting track or send us email.

Track 1. Social Computing

This track invites papers investigating social processes and practices in Hypermedia and Web 2.0 environments. These include tagging, filtering, voting, editing, trusting, and rating. These social processes result in many types of links between texts, users, concepts, pages, etc. We want to better understand the processes and practices themselves as well as the social, political, and semantic networks that result over time.

Track 2. Adaptive Hypermedia and Applications

This track invites papers reporting on theoretical, empirical, and methodological studies on adaptive hypermedia, including the application of adaptive hypermedia such as self organizing in varying domains and contexts. The scope includes all forms of Web and Hypermedia systems, including user modeling, recommender systems, and e-learning, as well as components of resulting systems (e.g, navigation).

Track 3. - Hypertext in Context

Hypertext tools are indispensable for e-learning and m-learning, and teaching Hypertext as a discipline in its own right -- including literary fiction, new scholarship and digital media -- plays a growing role in education. This track targets hypertext as both a tool and a discipline, as well as focusing on the use of spatial hypertext and Web 2.0 applications such as blogs, wikis and e-portfolios. We hope to highlight our understanding of links as a new component of writing and communication, and to increase our understanding of the way that they are used in multiple domains such as education, research, journalism, and literature.

CFP: NAACL-HLT 2010 Workshop on Semantic Search (SemanticSearch 2010)

NAACL-HLT 2010 Workshop on Semantic Search (SemanticSearch 2010)
June 5 or 6, Los Angeles, CA

Information retrieval (IR) research has been actively driven by the challenging information overload problem and many successful general-purpose commercial search engines. While the popularity of the largest search engines are a confirmation of the success and utility of IR, the identification, representation, and use of the often-complex semantics behind user queries has not yet been fully explored.

In this workshop we target methods that exploit semantics in search-related tasks. One of the major obstacles in bridging the gap between IR and Natural Language Processing (NLP) is how to retain the flexibility and precision of working with text at the lexical level while gaining the greater descriptive precision that NLP provides. We encourage contributions on automatic analysis of queries and documents in order to encode and exploit information beyond surface-level keywords: named entities, relations, semantic roles, etc.

This workshop is meant to accelerate the pace of progress in semantic search techniques by connecting IR and NLP, bridging semantic analysis and search methodologies, and exploring the potentials of search utilizing semantics. We also focus on forming an interest group from different areas of research, exploring collaboration opportunities, providing deeper insight into bringing semantics into search, and provoking or encouraging discussions on all of its potential.

We invite submissions on (but not limited to) the following topics:

• Query Parsing and Semantic Tagging
• Query Suggestion and Recommendation
• Query Expansion
• Query Intention Detection
• Web Query Analysis and Mining
• Semantic Annotation and Indexing
• Language Modeling for Information Retrieval
• Information Extraction and Summarization for Indexing and Search
• Question Answering
• Search Reranking Integrating Semantic Features
• Search Relevance Evaluation using Semantic Technology
• Topic Modeling and Semantic Tagging

IMPORTANT DATES

• Mar 1, 2010 Submissions due
• Mar 30, 2010 Notification of acceptance
• Apr 12, 2010 Camera-ready due

CFP: Workshop on Interoperable Social Multimedia Applications (WISMA 2010)

Workshop on Interoperable Social Multimedia Applications (WISMA 2010)
11th International Workshop of the Multimedia Metadata Community
Workshop venue: Universitat Politècnica de Catalunya, Barcelona (Spain)

In the Web 2.0, a growing amount of multimedia content is being shared on Social Networks. Due to the dynamic and ubiquitous nature of this content (and associated descriptors), new interesting challenges for indexing, access, and search and retrieval have arisen. In addition, there is a growing concern on privacy protection, as a lot of personal data is being exchanged. Teenagers (and even younger kids), for example, require special protection applications; while adults are willing to have a higher control over the access to content. Furthermore, the integration of mobile technologies with the Web 2.0 applications is also an interesting area of research that needs to be addressed; not only in terms of content protection, but also considering the implementation of new and enriched context-aware applications. Finally, social multimedia is also expected to improve the performance of traditional multimedia information search and retrieval approaches by contributing to bridge the semantic gap. The integration of these aspects, however, is not trivial and has created a new interdisciplinary area of research. In any case, there is a common issue that needs to be addressed in all the previously identified social multimedia applications: the interoperability and extensibility of their applications. Thus, the workshop is particularly interested in research contributions based on standards.

Hello Jose, do you speak English (UK)? Help translate Facebook into English

Facebook needs help:

Hello Jose, do you speak English (UK)?

Help translate Facebook into English (UK) so that it can be used by people all over the world, in all languages.

Click on the Translate Facebook button to add the Translations application, developed by Facebook, so that you can be part of the community of translators.

[Checkbox] I wish to participate in Facebook's language translation project and I agree to the Additional Terms Applicable to Translate Facebook

My answer was going to be yes, until I read the Additional Terms:

Terms Applicable to Translate Facebook

The Translate Facebook application collects translations, comments, suggestions, ideas, feedback and other information ("Submissions") from you and other users in connection with Facebook's language translation project to provide access to Facebook and applications and websites that use Facebook's platform in multiple languages (the "Project").

You understand that your participation in the Project is for the benefit of the Facebook user community as it will allow users whose participation is currently limited by language to more fully participate. You acknowledge that your participation in the Project is entirely voluntary, and you understand that no monetary or other compensation will be given to persons, including you, for Submissions. You may provide as much or as little input into the Project as you wish and can cease contributing to the Project at any time.

In consideration of Facebook's permitting you to participate in the Project and the benefits to the Facebook user community of which you are a member, you acknowledge and agree that any Submissions that you provide to Facebook will be owned by Facebook. Accordingly, you irrevocably assign to Facebook all right, title and interest, including all intellectual property rights, in and to all Submissions, and Facebook is entitled to the unrestricted use and dissemination of these Submissions for any purpose, commercial or otherwise, without acknowledgment, consent or monetary or other tangible compensation to you. To the extent that the foregoing assignment is or becomes invalid or unenforceable to any degree or for any reason, you grant Facebook an irrevocable, perpetual, exclusive, fully-paid-up, royalty-free, worldwide right and license, with the right to sublicense, to use, reproduce, display, perform, create derivative works of, distribute and otherwise exploit the Submissions in any manner.

Please note: Translate Facebook is subject to and governed by these Additional Terms Applicable to Translate Facebook (the "Additional Terms") as well as the Facebook Terms of Use. In the event of any conflict between these Additional Terms and the Facebook Terms of Use, these Additional Terms control. Capitalized terms that are not defined in these Additional Terms will have the definitions provided them in the Terms of Use. Facebook reserves the right, in our sole discretion, to change, modify, add, or delete portions of these Additional Terms at any time without further notice. If we do this, we will post the changes to these Additional Terms on this page and will indicate at the top of this page the date these terms were last revised. You agree to waive any specific notice of such changes, and your continued use and operation of Translate Facebook after any such changes constitutes your acceptance of the new Additional Terms. It is your responsibility to regularly check the Site to determine if there have been changes to these Additional Terms.

In other words, by helping Facebook you are giving your soul for free to Facebook. Ok, I think it does not pay.

What is doing Europe on children protection in Social Networks?

Just check the Safer Internet Programme: Raising awareness & empowering children.

Quoting:

Much of its efforts has focused on children and teenagers, who have become massive users of social networking sites, and active users of the Internet as a whole.

(...)

The European Commission is supporting self-regulation when it is broadly accepted by stakeholders and where it provides for effective enforcement. Therefore, the Commission welcomed the first self-regulatory agreement signed by major social networks active in Europe on Safer Internet Day, 10 February 2009, in Luxembourg.

(...)

• Increasing awareness about the risks linked to the Internet
• Encouraging the adoption of rules and principles by those who create new interactive tools (self-regulation)
• Involve children in creating a safer online environment
