Technique of information filtering is mainly applied to characteristic information service and bad information filtering, however the emergence of bad information always mixes up in the customer's interested information. For overcome the shortage of traditional information filtering only achieve one of aspects applies, through improving vector space model, while building up user filtering model, characteristic information and bad information in the meantime collections train, extraction the characteristic phrase and endow with weight, changing the weight of bad information into negative value, attaining to carry out characteristic service and bad information filtering one time, simplifying filtering process and improving filtering efficiency.
