Text Classification in Information Retrieval using Winnow

Text classification in Information Retrieval can be done by using a linear classifier. Linear learning algorithms classify documents by learning a linear separator based on the document features. Littlestone's Winnow is such as linear learning algorithm. I have described three learning algorithms, based on Littlestone's Winnow, which can be applied to perform this task. Modifications of the alg...

Fuzzy-Fingerprints for Text-Based Information Retrieval

This paper introduces a particular form of fuzzy-fingerprints—their construction, their interpretation, and their use in the field of information retrieval. Though the concept of fingerprinting in general is not new, the way of using them within a similarity search as described here is: Instead of computing the similarity between two fingerprints in order to access the similarity between the as...

Distributional Semantic Representation for Text Classification and Information Retrieval

The objective of this experiment is to validate the performance of the distributional semantic representation of text in the classification (Question Classification) task and the Information Retrieval task. Followed by the distributional representation, first level classification of the questions is performed and relevant tweets with respect to the given queries are retrieved. The distributiona...

Specificity Helps Text Classification

We examine the impact on classification effectiveness of semantic differences in categories. Specifically, we measure broadness and narrowness of categories in terms of their distance to the root of a hierarchically organized thesaurus. Using categories of four different levels degrees of broadness, we show that classifying documents into narrow categories gives better scores than classifying t...

Temporal Information Retrieval Temporal Information Retrieval

Temporal dynamics and how they impact upon various components of information retrieval (IR) systems have received a large share of attention in the last decade. In particular, the study of relevance in information retrieval can now be framed within the so-called temporal IR approaches, which explain how user behavior, document content and scale vary with time, and how we can use them in our fav...
