Mercure at TREC 2003 Web track - Topic Distillation Task
نویسندگان
چکیده
Mercure is an information retrieval system based on a connexionist approach and modeled by a multi-layer network. The network is composed of a query layer (set of query terms), of a term layer (representing the indexing terms) and of a document layer [Bougha 99]. Mercure includes the implementation of retrieval process based on spreading activation forward and backward through the weighted links. Queries and documents can be used either as inputs or outputs. The links between layers are symmetric and their weights are based on the tf-idf measure inspired by OKAPI [Robertson 00] and SMART term weighting.

Relevance Propagation for Topic Distillation UIUC TREC 2003 Web Track Experiments
In this paper, we report our experiments on the Web Track TREC-2003. We submitted five runs for the topic distillation task. Our goal was to evaluate the standard language modeling algorithms for topic distillation, as well as to explore the impact of combining link and content information. We proposed a new general relevance propagation model for combining link and content information, and exp...
متن کاملOverview of the TREC 2003 Web Track
The TREC 2003 web track consisted of both a non-interactive stream and an interactive stream. Both streams worked with the .GOV test collection. The non-interactive stream continued an investigation into the importance of homepages in Web ranking, via both a Topic Distillation task and a Navigational task. In the topic distillation task, systems were expected to return a list of the homepages o...

Hummingbird participated in 4 tasks of TREC 2003: the ad hoc task of the Robust Retrieval Track (find at least one relevant document in the first 10 rows from 1.9GB of news and government data), the navigational task of the Web Track (find the home or named page in 1.2 million pages (18GB) from the .GOV domain), the topic distillation task of the Web Track (find key resources for topics in the ...
متن کاملUMBC at TREC 12
We present the results of UMBC’s participation in the Web and Novelty tracks. We explored various heuristics-based link analysis approaches to the Topic Distillation task. For the novelty task we tried several methods for exploiting semantic information of sentences based on the SVD technique. We used SVD to expand the query and to filter redundant sentences. We also used a clustering algorithm...

The Web IR experiment of TREC, otherwise known as the Web track, investigated in its initial stages the strategies for the same ad-hoc retrieval task as was done previously with plain text documents. Although many TREC participants explored methods of leveraging non-textual sources of information such as hyperlinks and document structure, the general consensus among the early Web track particip...
