around, to find repeated keywords in the sentence.īoolean found = ntains(s.toLowerCase()) Asking if the sentence exists in the keywords, not the other If we don't, then the count should be 4, "Say" being excluded and "say" included. keywords = new () īy looking at it, the expected result would be 5 for "Say" + "come" + "you" + "say" + "123woods", counting "say" twice if we go lowercase. Split it (punctuation taken in consideration, as well): This way you can see which internal pages are given more emphasis to, which anchor texts are used for both. String sentence = "Say that 123 of us will come by and meet you, " Seeing what a web page links out to is one of the major steps of SEO diagnostics process. For example: // Base sentence (added punctuation, to make it more interesting): It must be noticed that common sentences (as the one in the original question) can have repeated keywords, therefore the search cannot just ask if a given keyword "exists or not" and count it as 1 if it does exist.

#HOW TO SEARCH A WEB PAGE FOR A WORD JAVA HOW TO#
I'm still learning java, one step at a time, so I'll see to that one in due time :-) How to generate MS word documents automatically I started to search how to accomplish this task and found the Apache POI library.We can easily work with MS Office documents (word, excel, etc.) with the Apache POI library. I don't quite understand what "where" means (is it an index in the sentence?), so I'll pass that one.

However, there could be expandable fields on the page that. You can search the visible HTML on a page by doing a search and find on the standard page.
#HOW TO SEARCH A WEB PAGE FOR A WORD JAVA MAC#
Looking back at the original question, we need to find some given keywords in a given sentence, count the number of occurrences and know something about where. When you need to search within a site for a certain word, use the Search and Find keyboard shortcuts on your Mac or PC. StringFinder finder = stringSearch.createFinder(text) example with StringSearchAlgorithmsĪhoCorasick stringSearch = new AhoCorasick(asList("123woods", "woods")) ĬharProvider text = new StringCharProvider("I will come and meet you at the woods 123woods and all the woods", 0) These could be found in libraries like Stringsearchalgorithms or byteseek. You can use an HTTP GET request and use an online random word service (like this one) to get a random word.This method requires internet connection. The first way takes more time but requires pretty much no storage space. Algorithms suitable for such a search would be Aho-Corasick, Wu-Manber, or Set Backwards Oracle Matching. Theres no built-in way in Java, but theres 2 ways you can do this. Multi pattern search will process each character of the text exactly once. Instantiate the Scanner class by passing the above retrieved InputStream object as a parameter. Invoke the openStream () method and retrieve the InputStream object. Instantiate the class by passing the URL of the desired web page as a parameter to its constructor. In worse case each character of the text will be processed p times where p is the number of patterns. Therefore, to read data from web page (using the URL class). Connect to the desired web page using the connect () method. One will have to start the whole search for every keyword pattern. The connect () method of the Jsoup class accepts an URL of a web page and connects to the specified web page and returns the connection object. Single pattern search is better, but not qualified, too. In worse case each character of the text will be processed l times (where l is the sum of the pattern lengths). Searching for exactly one keyword is optimized in java, searching for an or-expression uses the regex non deterministic automaton which is backtracking on mismatches. Java Pattern Search (with Matcher.find) is not qualified for doing that. This is a classical application for multi-pattern-search-algorithms. The solution seems to be long accepted, but the solution could be improved, so if someone has a similar problem:
