processes make it a challenging task to understand themselves. It was at this point that I began to rely on flowcharts to understand the requirements and to use this method for interactive design. Gradually, the flowchart shows its allure: the product manager likes it, and even engineers use it to guide development.
In the fall of 2008, I summed up my experience as an article titled "A Little Experience in drawing Web Flowcharts", published on my blog. The text immediately drew wide attention.

"Tsinghua" is to modify the "university". There is no need to emphasize who is right, but to know that in different applications there is a better particle size than the other.For example, in machine translation, the granularity of large translation effect is good, such as "Lenovo Company" if split into open, it is difficult to translate "Lenovo." But in the web search, small particle size will be better than the large, such as user query "Tsinghua" and not "Tsinghua University" can be found on

Xmldictionary type "Old Xu Notes 1"
As the meaning of its name, a Xmldictionary object is a map of many pairs of key-value. Much like a dictionary or glossary, xmldictionary can be used to replace simple expressions without losing any meaning. We often use this mechanism in our daily life, but we are not aware of its existence. Consider the following I said to my

In the fall of 2008, I summed up my experience as an article titled "A Little Experience in drawing Web Flowcharts", published on my blog. The text immediately drew wide attention. Various recommendations, reprints, discussions and follow-up articles are frequently appearing online, and even people follow the method
better show the corresponding results to meet the needs of users. Therefore, the more accurate analysis of query requirements, the coverage of query, the user satisfaction is greater. Requirement analysis is one of the most important and difficult places in box computing.
The easiest way to identify query needs is to check the thesaurus. For example, all the movies, TV series are collected in advance, put into the thesaurus, as long as the user input the word in the
) and incorporates many good ideas from the Dsssl (document style, semantic, and canonical language) developed in the SGML community.During the development of the XSL (which has been foreshadowed in Dsssl), it is found that the tasks performed during the preparation of the XML document for display can be divided into two phases: transformation and formatting. A transformation is the process of converting an XML document (or its in-memory notation) into another XML document. A format is the proce

Another solution is to discard the word-based indexing strategy using short-character sequences (such as the K-gram method for characters).4. Stop word: Some of the commonly used words are not worth much when the document and user needs are matched, and need to be removed from the
then given a glossary (vaocabulary), each message is represented by a eigenvector (the length of the eigenvector is the same as the length of the glossary). If the term I appears in the message XI is 1 otherwise 0 (P (xi|y) in addition to the model can be modeled as a Bayesian effort distribution, can also be modeled as a multi-item distribution). Finally, the message is classified by the input eigenvector
Automatic clustering of a series of articles can be used as the basis of the content-based recommendation engine. To achieve automatic text clustering, first perform word segmentation based on the articles described in Series 5, then, the term vector representation of the article is calculated, that is, the TF * IDF corresponding to each different word in the article is obtained. The specific calculation method is shown in Figure 5. Currently, KMean is the most widely used text automatic cluster

, and relational data models in SQL. Mapping from relational data models to Java object models in development is so complex that most developers never define object models for data; they simply write procedural Java code to manipulate the data tables in the underlying relational database. The end result: they simply cannot benefit from object-oriented development.
The EJB component system is designed to support distributed object computing. It also includes support for container-managed persist

Tip: the PE file with the extension name ".exe" does not usually contain an export table, but most. DLL files contain an export table. But note that this is not absolute. For example, if the. dll file is purely used as a resource, the export function exists in the. exe file with some special functions. So there is no such thing as absolute ...... Now, we will analyze the structure of the exported table.
Export table structure
The main component of an export table is a table contain

Last weekend, we released Cloud9 IDE in JSConf. eu and the corresponding GitHub project. In four days, the project received 340 people's attention and nearly 50 forks. Cloud9's slogan is "IED created by Javascripters for Javascripters", which is a bit recursive and means you can use the ide to make it more powerful. At the beginning of the Cloud9 project, pay special attention to this. Each function in Cloud9 is an extension ). When starting the
