    Synonym Detection Jobs

    Use this job to generate pairs of synonyms and pairs of similar queries. Two words are considered potential synonyms when they are used in a similar context in similar queries.

    Default job name

    COLLECTION_NAME_synonym_detection

    Input

    • Aggregated signals (the COLLECTION_NAME_signals_aggr collection by default)

    • Spell Correction job output (the COLLECTION_NAME_query_rewrite_staging collection by default)

    • Phrase Extraction job output (the COLLECTION_NAME_query_rewrite_staging collection by default)

    Output

    Synonyms (the COLLECTION_NAME_query_rewrite_staging collection by default)

    For best job speed and to avoid memory issues, use aggregated signals instead of raw signals as input for this job.

    Output from the Token and Phrase Spell Correction job and the Phrase Extraction job can be used as input for this job.

    To:

    Input

    This job takes one or more of the following as input:

    Signal data

    This input is required; additional input is optional. Signal data can be either raw or aggregated. The job runs faster using aggregated signals. When raw signals are used as input, this job performs the aggregation.

    Use the trainingCollection/Input Collection parameter to specify the collection that contains the signal data.

    Misspelling job results

    Token and Phrase Spell Correction job results can be used to avoid finding mainly misspellings, or mixing synonyms with misspellings.

    Use the misspellingCollection/Misspelling Job Result Collection parameter to specify the collection that contains these results.

    Phrase detection job results

    Phrase Extraction job results can be used to find synonyms with multiple tokens, such as "lithium ion" and "ion battery".

    Use the keyPhraseCollection/Phrase Extraction Job Result Collection parameter to specify the collection that contains these results.

    Keywords

    A keywords list in the blob store can serve as a blacklist to prevent common attributes from being identified as potential synonyms.

    The list can include common attributes such as color, brand, material, and so on. For example, by including color attributes you can prevent "red" and "blue" from being identified as synonyms due to their appearance in similar queries such as "red bike" and "blue bike".

    The keywords file is in CSV format with two fields: keyword and type. You can add your custom keywords list here with the type value "stopwords". An example file is shown below:

    keyword,type
cu,stopword
ft,stopword
mil,stopword
watt,stopword
wat,stopword
foot,stopword
feet,stopword
gal,stopword
unit,stopword
lb,stopword
wt,stopword
cc,stopword
cm,stopword
kg,stopword
km,stopword
oz,stopword
nm,stopword
qt,stopword

grey,stopword
brown,stopword
silver,stopword
light blue,stopword
light ivory,stopword
light grey,stopword
light brown,stopword
light silver,stopword
light green,stopword

    Use the keywordsBlobName/Keywords Blob Store parameter to specify the name of the blob that contains this list.

    Custom Synonyms

    For some deployments, there might be a need to use existing synonym definitions. You can import existing synonyms into the Synonym Detection Jobs as a text file. Upload your synonyms text file to the blob store and reference that file when creating the job.

    Output

    The output collection contains two tables distinguished by the doc_type field.

    The similar queries table

    If query leads to clicks on documents 1, 2, 3, and 4, and similar_query leads to clicks on documents 2, 3, 4, and 5, then there is sufficient overlap between the two queries to consider them similar.

    A statistic is constructed to compute similarities based on overlap counts and query counts. The resulting table consists of documents whose doc_type value is "query_rewrite" and type value is "simq". The similar queries table contains similar query pairs with these fields:

    query

    The first half of the two-query pair.

    similar_query

    The second half of the two-query pair.

    similarity

    A score between 0 and 1 indicating how similar the two queries are.

    All similarity values are greater than or equal to the configured Query Similarity Threshold to ensure that only high-similarity queries are kept and used as input to find synonyms.

    query_count

    The number of clicks received by the query_count query.

    To save computation time, only queries with at least as many clicks as the configured Query Clicks Threshold parameter are kept and used as input to find synonyms.

    similar_query_count

    The number of clicks received by the similar_query_count query.

    The synonyms table

    The synonyms table consists of documents whose doc_type value is "query_rewrite" and type value is "synonym":

    surface_form

    The first half of the two-synonym pair.

    synonym

    The second half of the two-synonym pair.

    context

    If there are more than two words or phrases with the same meaning, such as "macbook, apple mac, mac", then this field shows the group to which this pair belongs.

    similarity

    A similarity score to measure confidence.

    count

    The number of different contexts in which this synonym pair appears.

    The bigger the number, the higher the quality of the pair.

    suggestion

    The algorithm automatically selects context, synonym words or phrases, or the synonym_group, and puts it in this field.

    Use this field as the field to review.

    category

    Whether the synonym is actually a misspelling.
