HazyResearch DeepDive DeepDive is a system to extract value from dark data. Like dark matter, dark data is the great mass of data buried in text, tables, figures, and images, which lacks structure and so is essentially unprocessable by existing software. License: Apache 2 , . Apache Incuba...
Then substring uses the return value of lastIndexOf to extract the file name extension — that is, the substring from the period to the end of the string. This code assumes that the file name has a period in it; if the file name does not have a period, lastIndexOf returns -1, and...
String INPUT = "This line contains <the first value>, <the second value>, and <the third value>."; Let’s say we want to extract all “<…>” segments from the string above, such as “<the first value>” and “<the second value>“. To match these segments, we can use regex’...
input String or you need to reuse the pattern. Note that the pattern defined by regex is applied on the String from left to right and once a source character is used in a match, it can’t be reused. For example, regex “121” will match “31212142121” only twice as “_121___121...
