Based on several excellent forum contribution’s, I asked Michael Capes friend with big brain to review them and provide feedback. The result is a revision to the original script. See Forum posts for this article for details. We have also provided a test script and results. I have worked in this area for many years and this is by no means a complete solution suitable for very high volumes, however this article will provide a workable T-SQL solution for matching and grouping required for de duplication. In addition we will demonstrate how to cleans a string and remove special characters. However the list of prospective customers has some duplicate due to misspelling and or typos. As you can see from the list above we have a list of Customer Ids and First and Last names. For our exercise the last names are assumed to be correct. We want to create an output list that links the similar customers and also normalizes or standardizes the first names.
We claim as follows:
Three Ways to Search Smarter in The bigger and more complicated the database, the more talented its search capabilities need to be. These three techniques let you broaden the results returned by MySQL searches: A database doesn’t do users much good if they can’t find the data they’re searching for. The larger and more complex the database elements, the more sophisticated your searches have to be to return the information you need.
The three types of full-text searches are natural language, boolean, and query expansion, which broadens the results of a natural-language search based on automatic relevance feedback also called blind query expansion.

Here are some general guidelines to make your use of this site more enjoyable and productive for you At EE, the experts exchange answers and advice for points. If you look at the questions awaiting answers in this zone, you will see a lot of point questions. Your question is competing for the experts’ attention among those high-point questions. So as a matter of simple economics you might be able to envision which questions will get the experts’ attention first. We are experts, but not mind readers.
Inquiries that are broad, vague and hypothetical may not get answers that are as succinct and effective as inquiries that have actual URLs, complete code examples, and clearly expressed questions. Whenever possible, please provide the inputs and tell us what you want for the outputs. If you do not have the SSCCE , stop what you’re doing and create one, and post it with your question. And please accept that sometimes the right answer is, “Don’t do that — it doesn’t work that way.
If you have no test data, please create some. We do not want you to post “live” passwords and such. Instead, please set up a testbed and show us the links to that, instead of the live data.

Abstract With smartphone distribution becoming common and robotic applications on the rise, social tagging services for various applications including robotic domains have advanced significantly.
Though social tagging plays an important role when users are finding the exact information through web search, reliability and semantic relation between web contents and tags are not considered. Spams are making ill use of this aspect and put irrelevant tags deliberately on contents and induce users to advertise contents when they click items of search results. Therefore, this study proposes a detection method for tag-ranking manipulation to solve the problem of the existing methods which cannot guarantee the reliability of tagging.
Similarity is measured for ranking the grade of registered tag on the contents, and weighted values of each tag are measured by means of synonym relevance, frequency, and semantic distances between tags. Lastly, experimental evaluation results are provided and its efficiency and accuracy are verified through them.

Symbol ‘t’ occurs at positions 0 and 3, the rightmost occurence is at position 3. The occurrence function for a certain pattern p is stored in an array occ which is indexed by the alphabet symbols. For each symbol a A the corresponding value occ p, a is stored in occ[a]. The following function bmInitocc computes the occurrence function for a given pattern p.

Depending on the source and age of the data, you may not be able to count on the spelling of the name being correct, or even the same name being spelled the same way when it appears more than once. Discrepancies between stored data and search terms may be introduced due to personal choice or cultural differences in spellings, homophones , transcription errors, illiteracy, or simply lack of standardized spellings during some time periods.
These sorts of problems are especially prevalent in transcriptions of handwritten historical records used by historians, genealogists, and other researchers. A common way to solve the string-search problem is to look for values that are “close” to the same as the search target. Using a traditional fuzzy match algorithm to compute the closeness of two arbitrary strings is expensive, though, and it isn’t appropriate for searching large data sets.
A better solution is to compute hash values for entries in the database in advance, and several special hash algorithms have been created for this purpose. These phonetic hash algorithms allow you to compare two words or names based on how they sound, rather than the precise spelling. Soundex One such algorithm is Soundex , developed by Margaret K.

Block-based join algorithms in MariaDB employ a join buffer to accumulate records of the first join operand before they start looking for matches in the second join operand. This page documents the various block-based join algorithms. This new format allows: More efficient use of buffer space for null field values and field values of flexible length types like the varchar type Support for so-called incremental join buffers saving buffer space for multi-way joins Use of the algorithm for outer joins and semi-joins How Block Nested Loop Join works The algorithm performs a join operation of tables t1 and t2 according to the following schema.
The records of the first operand are written into the join buffer one by one until the buffer is full. For every read record r2 of table t2 the join buffer is scanned, and, for any record r1 from the buffer such that r2 matches r1 the concatenation of the interesting fields of r1 and r2 is sent to the result stream of the corresponding partial join.

Markus W Mahlberg 2, I wouldn’t presume that storing a million strings requires sharding; you should be able to comfortably wrangle that on a modern laptop: I would also not recommend unacknowledged write concerns if you care about the data. A difference between default acknowledged writes and unacknowledged is that unack’d writes ignore insertion errors for example, duplicate key exceptions. A more appropriate approach for speeding up insertion would be to use Bulk Inserts.
You can’t delete documents from a capped collection, and the documents are maintained in insertion order. If you need to scale writes beyond a single server, you should use a normal sharded collection. And you should really show me how an upsert should trigger a duplicate key exception. I am curious on how that should work. Bulk inserts, on the other hand, have the problem that a bulk insert for a single document simply doesn’t make sense.

However, this optimization makes it impossible to read off the minimal series of edit operations. It achieves this by only computing and storing a part of the dynamic programming table around its diagonal. Various algorithms exist that solve problems beside the computation of distance between a pair of strings, to solve related types of problems. Hirschberg’s algorithm computes the optimal alignment of two strings, where optimality is defined as minimizing edit distance.
Approximate string matching can be formulated in terms of edit distance. Ukkonen’s algorithm takes a string p, called the pattern, and a constant k; it then builds a deterministic finite state automaton that finds, in an arbitrary string s, a substring whose edit distance to p is at most k  cf. A similar algorithm for approximate string matching is the bitap algorithm , also defined in terms of edit distance.
Levenshtein automata are finite-state machines that recognize a set of strings within bounded edit distance of a fixed reference string. Instead of considering the edit distance between one string and another, the language edit distance is the minimum edit distance that can be attained between a fixed string and any string taken from a set of strings.
