Query Reformulation and Refinement Using NLP-Based Sentence Clustering
We have developed an interactive query refinement tool that helps users search a knowledge base for solutions to problems with electronic equipment. The system is targeted towards non-technical users, who are often unable to formulate precise problem descriptions on their own. Two distinct but interrelated functionalities support the refinement of a vague, non-technical initial query into a mor...
متن کاملUsing NLP Techniques for Meaning Negotiation
This paper describes an automatic algorithm of meaning negotiation that enables semantic interoperability between local overlapping and heterogeneous ontologies. Rather than reconciling differences between heterogeneous ontologies, this algorithm searches for mappings between concepts of different ontologies. The algorithm is composed of three main steps: (i) computing the linguistic meaning of...
متن کاملUsing NLP techniques for file fragment classification
The classification of file fragments is an important problem in digital forensics. The literature does not include comprehensive work on applying machine learning techniques to this problem. In this work, we explore the use of techniques from natural language processing to classify file fragments. We take a supervised learning approach, based on the use of support vector machines combined with ...
متن کاملTowards Enhanced Opinion Classification using NLP Techniques
Sentiment mining and classification plays an important role in predicting what people think about products, places, etc. In this piece of work, using basic NLP Techniques like NGram, POS-Tagged NGram we classify movie and product reviews broadly into two polarities: Positive and Negative. We propose a model to address the problem of determining whether a review is positive or negative, we exper...
متن کاملSibyl: AAC System Using NLP Techniques
This paper presents Sibyl, a new AAC (Augmentative and Alternative Communication) computer system, that aims at improving text typing for persons with sever speech and motor impairments. Typical AAC systems display virtual keyboard on screen which enables key selection via a few switches device. However, text typing is cumbersome. Sibyl aims at allowing faster typing by means of two predictive ...
