Social Media have been able to shift the way information is generated and consumed. At first, information was generated by one person and “consumed” by many people, but nowadays most part of the information available in the Web is generated by users, which has changed the needs in information access and management. Social Networks like Facebook or Twitter manage tens of PB of information, with flows of hundreds of TB per day, and hundreds of billions of relationships.

User generated content provides an excellent scenario to apply the metaphor of mining any kind of information. In a social media context, users create a huge amount of data where we can look for valuable nuggets of knowledge by applying diverse search (information retrieval) and mining techniques (data mining, text mining, web mining, opinion mining). In this kind of data, we can find both structured information (ratings, tags, links) and unstructured information (text, audio, video), and we have to learn how to combine existing techniques in order to take advantage of the existing information heterogeneity while extracting useful knowledge.
The primary goal of this special issue of ACM Transactions on Intelligent Systems and Technology is to foster research in the interplay between Social Media, Data/Opinion Mining and Search, aiming to reflect the actual developments on technologies that exploit user generated contents.

Topics of Interest

We invite researchers and professionals from a broad range of disciplines to submit to this special issue. Papers may encompass any or all of the following types of works: foundational theoretical analyses, modelling, simulation, and empirical studies. Moreover, authors may examine different aspects of search and mining user generated contents in a variety of possible contexts. Topics of interest include, but are not limited to:


A) Mining Social Media

  • Social networks analysis/mining
  • Tagging/links/graphs analysis and mining
  • Community detection and evolution
  • Influence, trust and privacy analysis
  • Social media monitoring/analysis

SGP's 1st Funding Round

. Thursday, April 15, 2010
3 comments

We are now finishing our first funding series for SGP (Social Gaming Platform), a spin-off from MAVIR.

Our main activity is the development of technologies and services in the Internet, focusing on Social Media and E-Commerce. We have developed a Recommender System that can be integrated within any website via a REST API, and we have also developed Wipley, a social network for videogamers where we have integrated our recommender system.

SGP has been founded by 3 engineers (Francisco Carrero, Borja Monsalve and myself), with a large experience on founding start-ups, and R&D projects. We have been part of 15 R&D projects, funded by several entities like European Commission or the Spanish R&P Plan.

We are ready to commercialize our products, and that's why we have been looking for funding the last months. We have estimated a funding need of €550K for the two first years. Until this moment we have been granted with a CDTI's PID project with a total amount of €350K and we have obtained 0ther €100K from FFF, so we only need extra €100K.

If you are interested on investing at our company, please, contact us at the following e-mail: francisco.carrero(a)wipley.com. We'll give you all the information you need in order to evaluate the investment.

This year's editions of RecSys (ACM Recommender Systems) and ECML/PKDD (European Conference on Machine Learning) will be held in Barcelona. ECML will be from 20th to 24th of September (Monday to Friday), and RecSys will start on Sunday (26th) and will finish 30th of September (thursday).

There is a clear topic relation between RecSys and ECML, in fact most of actual RecSys approaches has been proben in other fields (like data-mining, machine learning, information retrieval, etc.) before. For whom, like me, work around the two fields, is a great opportunity to assist two great conference in a single travel, and discover Barcelona, that is a really great city.

Opinion Mining/Sentiment Analysis resources

. Tuesday, March 02, 2010
50 comments

We're actually trying to integrate Opinion Mining techniques into some of our future products, and I've been reading a lot about Opinion Mining and I found the survey "Opinion Mining and Sentiment Analysis" by Bo Pang and Lillian Lee a really valuable resource, as it contains an extensive bibliography, publicly available datasets and lexical resources, etc.

Another interesting source of contents has been WOMSA workshop (1st Workshop on Opinion Mining and Sentiment Analysis), held in November 2009, with some up-to-date applications.

I also found interesting that Evri API that offer some sentiment-related details about some entities that are indexed in Evri.

I'm convinced we'll see a lot of Opinion Mining powered applications and services during the next years, it's a really interesting field in terms of its applications in marketing, social media...

++++++++++
Motivation
++++++++++

During the last years, researchers and practitioners of the Semantic Web have progressively consolidated a number of very important achievements. Formal languages have been standardized to define ontology-based knowledge representations, logic formalisms and query models. Ontology engineering methodologies and tools have been proposed to ease the designing and populating of ontological knowledge bases. Reasoning engines have been implemented to exploit inference capabilities of ontologies, and semantic-based frameworks have been built to enrich the functionalities of Web services. These achievements are the pillars to deal with the complex challenge of bringing semantics to the Web.

The above gives a new ground to extend the focus of the Semantic Web by engaging it in other communities, where semantics can play an important role. The available semantic knowledge bases can be used to enrich and link additional repositories, ontology engineering techniques can be utilized to properly design and build ontologies in further real-world domains, and inference and query mechanisms can enhance classic information management and retrieval approaches.

Among these communities, this workshop aims to attract the attention of students and professionals both from academia and industry who take benefit of semantic-based techniques and technologies in within-application Adaptation, Personalization and Recommendation approaches. In parallel to the progress made in the Semantic Web research topics, there have been appearing works in the above areas that use ontologies to model the user’s preferences, tastes and interests, and exploit these personal features together with meta-information about multimedia contents in order to provide the user with adaptation and personalization capabilities for different purposes such as information retrieval and item recommendation.

Moreover, with the advent of the Web 2.0 (also called the Social Web), the potential study and development of those approaches have increased exponentially. Social networks allow people to provide explicit relationships with others, and find out implicit user similarities based on their profiles. Social tagging services offer the opportunity to easily create and exploit personal knowledge representations. Wiki-style sites represent an environment where the community contributes and shares information, and blogs are media in which users express subjective opinions.

In all of these scenarios, adaptation, personalization and recommendation are core functionalities. However, the understanding and exploitation of the semantics underlying user and item profiles are still open issues.

++++++++++++++++++
Topics of interest
++++++++++++++++++

The workshop will focus on establishing user/usage models for adaptation, personalization and recommendation approaches for the Social-semantic Web.

Topics of interest include, but are not limited to the exploitation of the Web of Data, the identification of semantics underlying social annotations of multimedia contents, and the application of semantic-based techniques and technologies in research fields related to:

* Personalized access to multimedia content
* Content-based recommendation and collaborative filtering
* Adaptive exploration of multimedia content
* Adaptive user interfaces for multimedia content browsing and searching
* Community extraction and exploitation
* Social networks analysis for collaborative recommendation
* User profile construction based on social tagging information
* Context-aware multimedia content access and delivery
* Mobile and ubiquitous multimedia content access and delivery

Markus Strohmaier is compiling a list of social tagging datasets available for research. Actually the list contains 8 datasets, but it's being actualized according to the comments made on Markus' blog. It seems a good place to find interesting datasets to work on, and also to share the actual datasets we're working on.

From Search to Recommender Systems

. Thursday, December 03, 2009
9 comments

Tech-companies rule the Web, and you can see that analyzing some of the biggest Internet companies like Google and Amazon. Google is the Intelligent Systems reference company due to their search engine, but also for the big quantity and quality of different technologies tehy develop like automated translation, user profiling, context management or even image processing.

Amazon is a e-commerce store, and it seems not so correlated with technology as Google, but the vision of Jeff Bezos and their commitment to technology have allowed them to grow like anyone before in the e-commerce market. For Bezos, an online store should not limit their catalog to a few items, online stores should contain millions of products, and should personalize the user experience of their users. His vision was clear: "if you have 3 million customers in the Web, I should have 3 million online stores", and then the recommender system ruled Amazon.

Both technologies (search and recommender systems) are useful for the Information Overload problem we suffer nowadays. But they're radically different from their conception. Search engines need the users to express their needs in textual form, and then process that query and retrieve the most relevant documents according to that query. Recommender Systems analyze the behaviour (and other kind of data) of the user in a website and then are able to choose the products or contents more likely to interest the user. Both approaches are useful, but until the moment recommender systems are not as popular as search engines.

But we are in a turnaround in the Web, as the way information is generated and consumed has changed. Nowadays, due to the success of Social Media sites like Facebook or Twitter, and even to the success of previous technologies as RSS, we receive a lot of information in a passive way: we don't ask directly to receive that information, but we receive it. Until the moment, the problem was to find some important information, but now the problem is turning into choose what information I already receive is relevant to me. That's why I think recommender systems will replace in popularity to search engines in the future.
