As the field progressed, increasingly complex strategies have been proposed (either by combining the above strategies or completely different). Some of these are based on methods developed in fields such as: econometrics, financial mathematics, stochastics and even artificial intelligence and multi-agent systems.

我们提出了VIPS(Vision-based page segmentation)算法用以提取给定网页的语义结构。这种语义结构是层次性的结构,在该结构中,每一个结点代表一个语义块。每一个语义块都定义一个DOC值来描述该语义块内部内容的关联性。DOC的值越大,则表明语义块内部的内容,它们之间的联系越紧,反之越松散。VIPS算法充分利用了Web页面的布局特征:它首先从DOM树中提取出所有的合适的页面块,然后根据这些页面块检测出它们之间的所有的分割条,包括水平和垂直方向。最后基于这些分割条,Web页面的语义结构将被重新构建。对于每一个语义块又可以使用VIPS算法继续分割为更小的语义块。因此整个VIPS算法是自顶向下,非常高效的。

Some of the very best algorithms of the computer age are highlighted in the January/February 2000 issue of Computing in Science & Engineering, a joint publication of the American Institute of Physics and the IEEE Computer Society. Guest editors Jack Dongarra of the University of Tennessee and Oak Ridge National Laboratory and Francis Sullivan of the Center for Computing Sciences at the Institute of Defense Analyses put together a list they call the "Top Ten Algorithms of the Century".

How do you convert written words into math? Goldman says it takes a combination of algebra and geometry. Imagine an object floating in space that has an edge for every known scrap of information. It's called a polytope and it has near-infinite dimensions, almost impossible to conjure up in our earthbound minds. It contains every topic written about in the press. And every article that Inform processes becomes a single line within it. Each line has a series of relationships. A single article on Bordeaux wine, for example, turns up in the polytope near France, agriculture, wine, even alcoholism. In each case, Inform's algorithm calculates the relevance of one article to the next by measuring the angle between the two lines.

Welcome to my computer programming algorithms directory. I am hoping to provide a comprehensive directory of web sites that detail algorithms for computer programming problems.

This is a dictionary of algorithms, algorithmic techniques, data structures, archetypical problems, and related definitions. Algorithms include common functions, such as Ackermann's function. Problems include traveling salesman and Byzantine generals. Some entries have links to implementations and more information. Index pages list entries by area and by type. The two-level index has a total download 1/20 as big as this page.

Suppose you have to perform a case-insensitive text search over a Unicode string. You probably know that Boyer-Moore algorithm is the most efficient algorithm for such a task. This article shows how to implement the Boyer-Moore algorithm for Unicode, using C#.

Collaborative Filtering Recommendation Systems are software systems that enable communities to perform collaborative filtering. At the center of a collaborative filtering system is a collaborative filtering recommendation engine – the software system responsible for the computation involved in collaborative filtering. The recommendation engine is responsible for analyzing ratings, determining who is neighbor to whom, and computing the predictions and recommendations. The CoFE is one such recommendation engine. We refer to the people who provide ratings to the recommender engine (and request recommendations and predictions) as users.

The Porter stemming algorithm (or ‘Porter stemmer’) is a process for removing the commoner morphological and inflexional endings from words in English. Its main use is as part of a term normalisation process that is usually done when setting up Information Retrieval systems.
