Sometimes, very simple mathematical methods can accomplish very complex tasks. The first two parts of the series are good examples. Only by counting the frequency of words can you find keywords and similar articles. Although they are not the best

rack products, such as 5hu-288 core fused fiber wiring frame, its fusion fiber modular structure, self-equipped with cable, more than conventional 1hu-24 core fiber cable rack can save 80% of cabinet space.2.3.2 Access Layer FD weak motor room (IDF) planningCompared to the core layer and the aggregation layer, the access layer weak motor room of the

the Ortronics six cable, which is connected to the user's 500 data racks, which are eventually wired and exported on the six-type wiring rack panels of the Ortronics 24-port. Although the Tek system is currently running at a speed of 100M, the design of the CLARITYTM system can be smoothly transferred to the future using four pairs of cable Full-duplex transmission applications. For four different networks, there are four different locations in each

This is a creation in Article, where the information may have evolved or changed. Above we have said some inverted index of things, and also know how to implement an inverted index to complete the retrieval function, then how to sort after the search is finished, this article simply about the inverted index of the text correlation sort, because the sort is too complex, we are here to talk about the text of the relevance of the sort, And it's the simplest sort of td-

the primary network data are placed in the Central Data Center of the network. Each floor has a secondary network device, which is vertically connected through optical fiber cables. ◆ Set up an MDF vertical distribution frame in the host machine room to manage the speech and data points of the entire building;◆ According to the architectural design, the building is equipped with Weak Current wells, and distribution lines are arranged on each floor in the weak current well,

server to handle a single task. There is no virtual server or management layer in the real product cluster, so there is no excess performance loss. Hadoop works best on Linux systems and operates directly on the underlying hardware infrastructure. This means that Hadoop is actually working directly on the virtual machine. This has unparalleled advantages in cost, ease of learning and speed. Hadoop cluster Above is the construction of a typical Hadoop cluster. A series of racks are connected by

Before parsing the Lucene search process, it is necessary to separate the Lucene score formula and describe the meaning of each part. Because of Lucene's search process, a very important step is to gradually calculate the scores of each part. Lucene's scoring formula is very complex, as follows: Before derivation, we will introduce the meaning of each part one by one: T: Term. The Term here refers to the Term that contains the domain information, that is, the title: hello and content: hello

code, and deploy the Lucene-driven full-text search cluster. You will find it works very well, fast and accurate.Then you wonder: Why is Lucene so awesome?This article, which focuses on Tf-idf,okapi BM-25 and the general relevance score, and the next article (main introduction index) will tell you the basic concepts behind full-text search.CorrelationFor each search query, it is easy to define a "related score" for each document. When a user makes a

pair of UTP trunk cable, and reserves the trunk number based on the ratio of 20% of the total number of voice information points in each wiring room. Therefore, the logarithm of each trunk cable can be estimated. To each wiring management room, a 12-core multi-mode optical cable is used as the trunk. 5. device room Voice and data distribution frames are mainly used to interconnect MDF in other zones, and place servers (computer network devices, etc.), program-controlled switches (PABX), and

, functional words have no practical meaning, such as "the", "is", "at", "which" and so on. Another category is lexical words, such as "want" and so on. Discontinued words have no meaning for the sentiment classification of movie reviews, so we need to delete some of the discontinued words. Use the Nltk.download function to get the deactivation words provided by NLTK and to remove the deactivation words from the movie comments using these deactivation words. The NLTK library provides a total of
