WORK PROPOSALS

All Master and PhD students interested in Lexical Semantics, Textual Entailment, Web Personalization, Web Collaboration, Temporal Information Retrieval, Automatic Summarization and Terminological Ontologies are welcome to collaborate. For prospective students, here are some ideas of possible works.
 

Multi-Document Summarization

Multi-Document Summarization systems must produce summaries about different texts keeping track of redundant information but also contradictory information and also additional information. We are particularly interested in finding redundant information as well as contradictory information using techniques such as text assymetric similarity and textual entailment.

 

Multimedia Multimodal Information Retrieval

Multimedia Information Retrieval is an important trend in research. We are particularly interested in Spatio-Temporal Image Retrieval, which objective is to retrieve web images for a text query with a spatio-temporal intent. For that purpose, multimodal (text and image) characteristics are used.

 

Efficient Computing of Non-Contiguous Multiword Units

Computing statistics of non-contiguous substrings can be overwhelming when gigabytes of texts may be processed. For this purpose, specific algorithms must be proposed to improve the computation efficiency of multiword units. For that purpose, we study specific text algorithms which may handle contiguous and non-contiguous strings.

 

Mobile Adaptative Web

Tailoring interfaces in the context of Human Computer Interaction is important with new mobile devices. In this context, we are particularly interested in studying personalized and collaborative web search using micro-ontologies.

 

Automatic Construction of Ontologies

Terminological ontologies are built to allow reasoning about texts. In this context, we are particularly interested in studying the automatic construction of ontologies based on a pretopological framework with different types of similarity measures.

 

Haptic Access to Web Pages

Visually Impaired People (VIP) are info-included. In the context of search engines, we are particularly interested in finding new haptic ways to interact with web pages. The overall idea is to allow blind or disabled users to understand the web page layouts without seeing them.

 

Search Engines for Kids

The WWW is full of prohibited contents for children. In this context, we are particularly interested in developping methodologies that correctly identify prohibited contents across domains.
