Finding Hashtags in Elasticsearch 1.7.Unfortunately, both of those result in removing the hashtag. Instead of using these default analyzers, we clearly need to build out a custom one for our use case. Our initial approach, was to leave everything as is, but treat the and @ symbols as alphanumeric characters as well. To do this we did the following.: curl XPUT https//localhost9200/test_mapping: d settings" analysis" filter" hashtag_as_alphanum" type" word_delimiter, type_table: ALPHANUM, @" ALPHANUM" analyzer" hashtag" type" custom, tokenizer" whitespace, filter" lowercase, hashtag_as_alphanum." In the above example, we are keeping everything the same since the standard analyzer uses a lowercase filter which indexes everything in lowercase to avoid case sensitivity, and the whitespace tokenizer which ignores all characters that are alphanumeric a-z0-9. However, the twist we are throwing at elasticsearch here is that the and @ symbols are also considered alphanumeric, so they will not be ignored by the whitespace analyzer, and the regex of what it is looking for is now a-z0-9@. |

While working on different aspects of NLP, you may find yourself running into one of the following tasks quite often.: Normalization, Stemming and Lemmatization. Part of Speech tagging. While there a number of tools that can help you in the process, most of them open source as well, Elastic Search handles most of these operations out of the box. In this example, we can see how elastic search cleans up the stop words.: For example, by relying on the default set of stop-words on ES, one can easily test the features. |
