tntsearch - A fully featured full text search engine written in PHP

•    PHP

---

We created also some demo pages that show tolerant retrieval with n-grams in action. The package has bunch of helper functions like jaro-winkler and cosine similarity for distance calculations. It supports stemming for English, Croatian, Arabic, Italian, Russian, Portuguese and Ukrainian. If the built in stemmers aren't enough, the engine lets you easily plugin any compatible snowball stemmer. Some forks of the package even support Chinese. Unlike many other engines, the index can be easily updated without doing a reindex or using deltas.

SymSpell - 1 million times faster through Symmetric Delete spelling correction algorithm

•    CSharp

---

Spelling correction & Fuzzy search: 1 million times faster through Symmetric Delete spelling correction algorithm The Symmetric Delete spelling correction algorithm reduces the complexity of edit candidate generation and dictionary lookup for a given Damerau-Levenshtein distance. It is six orders of magnitude faster (than the standard approach with deletes + transposes + replaces + inserts) and language independent.

Zingg - Scalable fuzzy matching for data mastering, deduplication and entity resolution

•    Java

---

Zingg is a scalable fuzzy matching for data mastering, deduplication and entity resolution. Real world data contains multiple records belonging to the same customer. These records can be in single or multiple systems and they have variations across fields which makes it hard to combine them together, especially with growing data volumes. Zingg integrates different records of an entity like customer, patient, supplier, product etc in same or disparate data sources.

liquidmetal - :sweat_drops::metal: A mimetic poly-alloy of the Quicksilver scoring algorithm, essentially LiquidMetal

•    Javascript

---

Flex matching short abbreviations against longer strings is a boon in productivity for typists. Applications like Quicksilver, Alfred, LaunchBar, and Launchy have made this method of keyboard entry a popular one. It's time to bring this same functionality to web controls. LiquidMetal makes scoring long strings against abbreviations easy.If you like this project, buy me a coffee, donate via Gratipay, or book a session with me on Codementor.

closestmatch - Golang library for fuzzy matching within a set of strings :page_with_curl:

•    Go

---

closestmatch is a simple and fast Go library for fuzzy matching an input string to a list of target strings. closestmatch is useful for handling input from a user where the input (which could be mispelled or out of order) needs to match a key in a database. closestmatch uses a bag-of-words approach to precompute character n-grams to represent each possible target string. The closest matches have highest overlap between the sets of n-grams. The precomputation scales well and is much faster and more accurate than Levenshtein for long strings.closestmatch is more accurate than Levenshtein for long strings (like in the test corpus).

refinr - Cluster and merge similar char values: an R implementation of Open Refine clustering algorithms

•    C++

---

refinr is designed to cluster and merge similar values within a character vector. It features two functions that are implementations of clustering algorithms from the open source software OpenRefine. The cluster methods used are key collision and ngram fingerprint (more info on these here). In addition, there are a few add-on features included, to make the clustering/merging functions more useful. These include approximate string matching to allow for merging despite minor mispellings, the option to pass a dictionary vector to dictate edit values, and the option to pass a vector of strings to ignore during the clustering process.
