    摘要: Methods and computer-readable media are provided for ranking search results using feature extraction data. Each of the results of a search engine query is parsed to obtain data, such as text, formatting information, metadata, and the like. The text, the formatting information and the metadata are passed through a feature extraction application to extract data that may be used to improve a ranking of the search results based on relevance of the search results to the search engine query. The feature extraction application extracts features, such as titles, found in any of the text based on formatting information applied to or associated with the text. The extracted titles, the text, the formatting information and the metadata for any given search results item are processed according to a field weighting application for determining a ranking of the given search results item. Ranked search results items may then be displayed according to ranking.

    摘要: A method and system for reducing interference in a wireless communication network is disclosed. The wireless communication network has at least one base station using an antenna array and one or more code channels to receive or transmit one or more communication signals from or to a plurality of terminals used by one or more users. A signal received by the antenna array carries one or more training sequences and a traffic signal in a frame. After estimating a spatial signature and joint channel response model per user based on the training sequences, one or more spatial weights are found based on the estimated spatial signature and joint channel response model to maximize a signal to noise ratio. A joint detection matrix is then formed based on the estimated spatial weights, the joint channel response model, and a user code channel assignment. After code correlating a traffic signal to obtain one or more user specific multi-antenna signals, a spatial combining is performed on one or more multi-antenna signals associated with each user to generate scalar symbol estimates. Thereafter, a joint detection is done based on the scalar symbol estimates using the joint detection matrix. Similar techniques can be used for downlink communications.

    摘要: A method for extracting key terms and associated key terms for use in text mining is provided. The method includes receiving unstructured text documents, such as emails over a customer service system. Term candidates are extracted based on identifying consecutive word strings satisfying a context independency threshold. Term candidates are weighted using mutual information to generate a list of weighted terms. The weighted terms are then recounted. Terms are associated based on Chi-square values. Associated terms can then be used for information retrieval. A user interface can be personalized with individual user profiles.

    摘要: A method of training a classifier includes applying a first classifier to a first set of unlabeled data to form a first set of labeled data. The first classifier is able to assign data to classes in a first set of classes. A second classifier is applied to a second set of unlabeled data to from a second set of labeled data. The second classifier is able to assign data to classes in a second set of classes that is different from the first set of classes. The first and second sets of labeled data are used to retrain the first classifier.

    摘要: In one aspect, the present disclosure describes a process for maintaining file allocation tables (FATs) for a volume of storage medium. The process includes triggering, by a write operation, modification of data in an existing sector of a data file by writing of data to a new sector of the storage medium. The process also includes writing revised used/unused sector information into one FAT and setting a variable indicative of a number of FATs (NOF) to a first value. The process additionally includes copying the one FAT to another FAT and re-setting the variable to a second value.
