  2. Lesk algorithm - Wikipedia

    en.wikipedia.org/wiki/Lesk_algorithm

    for every sense of the word being disambiguated one should count the number of words that are in both the neighborhood of that word and in the dictionary definition of that sense; the sense that is to be chosen is the sense that has the largest number of this count. A frequently used example illustrating this algorithm is for the context "pine ...

  3. Skip list - Wikipedia

    en.wikipedia.org/wiki/Skip_list

    For example, to find the node in the fifth position (Node 5), traverse a link of width 1 at the top level. Now four more steps are needed but the next width on this level is ten which is too large, so drop one level. Traverse one link of width 3. Since another step of width 2 would be too far, drop down to the bottom level.

  4. Aho–Corasick algorithm - Wikipedia

    en.wikipedia.org/wiki/Aho–Corasick_algorithm

    In this example, we will consider a dictionary consisting of the following words: {a, ab, bab, bc, bca, c, caa}. The graph below is the Aho–Corasick data structure constructed from the specified dictionary, with each row in the table representing a node in the trie, with the column path indicating the (unique) sequence of characters from the root to the node.

  5. Hash table - Wikipedia

    en.wikipedia.org/wiki/Hash_table

    In computing, a hash table is a data structure that implements an associative array, also called a dictionary or simply map; an associative array is an abstract data type that maps keys to values. [2] A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value ...

  6. Linked list - Wikipedia

    en.wikipedia.org/wiki/Linked_list

    In the above example, ListHead would be set to 2, the location of the first entry in the list. Notice that entry 3 and 5 through 7 are not part of the list. These cells are available for any additions to the list. By creating a ListFree integer variable, a free list could be created to keep track of what cells are available. If all entries are ...

  7. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    The dictionary problem is the classic problem of designing efficient data structures that implement associative arrays. [2] The two major solutions to the dictionary problem are hash tables and search trees .

  8. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    Flow diagram a C-style for loop, representing the following code: for(i=0;i<5;i++) printf("*"); The loop will cause five asterisks to be printed. Flowcharts are used to design and document simple processes or programs. Like other types of diagrams, they help visualize the process.

  9. k-SVD - Wikipedia

    en.wikipedia.org/wiki/K-SVD

    In applied mathematics, k-SVD is a dictionary learning algorithm for creating a dictionary for sparse representations, via a singular value decomposition approach. k-SVD is a generalization of the k-means clustering method, and it works by iteratively alternating between sparse coding the input data based on the current dictionary, and updating the atoms in the dictionary to better fit the data.
