A Text Filtering Module Based on Lexical Chain

Abstract: In this paper we first give some information about the text filtering and the defects in VSM(Vector Support Machine),then we introduce the concept of lexical chain,give a model that build a profile based on lexical chain.We first analyse the text,then express the text with lexical chain.We use this lexicalchained profile to sift the information which may be of the user's interest.A filtering system should be able to adapt to user's interest changes,so we automatically modify the user model to recognize the changes.Experimental results show that the methods can improve the text filtering performance.

An Automatic Segmentation Method of Microscopic Cell Image

Abstract: Because of the nature of cell image and the influence of microscope,automatic segmentation for microscopic cell image becomes one difficult question.Because edge detection accurately indicates the edge points of the image, we present the edge detection algorithm based on region homogeneity measure. Then we can attain the initial contour automatically and fit the initial contour to true contour based on edge points using active contour models. At last we can realize the automatic segmentation of cell image.

Web Information Extraction Based on Ontology

Abstract: Electronically available data on the Web is exploding at an ever increasing pace.Much of this data is unstructured,which makes searching hard and traditional database querying impossible.For these kinds of documents we present a new approach to extracting information based on an application ontology that describes a domain of interest.For each unstructured document of interest,we extract its constants and and apply a recognizer to organize extracted constants as attribute values of tuples in a generated database schema.Our experiment data is come from World Wide Web.

The Research of Query Technique Based on the Fuzzy Theory

Abstract: In the realism living,the objects of query involve a great deal of fuzzy data besides accurate data. The traditional query is unable to satisfy the need. In this paper fuzzy theory and database system are combined, new data query technique is provided. The format of the fuzzy query command is set up;many fuzzy query sentences are constructed and applied in an instance.It is confirmed by the instance's running results that the query's effect is definite.A calculates formula for nature language is set up,which is closer to the meanings of the nature language. A theoretical frame is built for query in the fuzzy database. 

An Image Retrieval Method Based on Dominant Color Matching

Abstract: As an important visual info, color is now widely used in image retrieval. The dominant color can reflect the main situation of an image. It's essential is to present the image by means of less color and make little difference between the new image and the original image. So we propose a new clustering algorithm to contribute similar colors into some dominant colors, that is, to quantize color. After that , we can use histogram to show the distributing info of dominant colors and use histogram intersection algorithm to search similar images from the image repository. The result of the experiment is satisfied.
