States, what percentage of them are "nursery school" or "child care"? Of all the unigrams, what percentage of them are "kindergarten"? Here, you can see that use of the phrase "child care" started to rise. It peaked shortly after 1. Interestingly, the results are noticeably different when the.

A few features of the Ngram Viewer may appeal to users who want to dig a. Wildcard search. When you put a * in place of a word, the Ngram Viewer will display the top ten substitutions. For instance, to find the most popular words following "University of", search for "University of *". You can right click on any of the replacement ngrams to collapse them all into the original wildcard query, with the result being the yearwise sum of the replacements. A subsequent right click expands the wildcard query back to all the replacements. Note that the Ngram Viewer only supports one * per ngram. Note that the top ten replacements are computed for the specified time range. You might therefore get different replacements for different year ranges. We've filtered punctuation symbols from the top ten list, but for words that often start or end sentences, you might see one of the sentence boundary symbols (_START_ or _END_) as one of the replacements. Inflection search. An inflection is the modification of a word to represent various grammatical categories such as aspect, case, gender, mood, number, person, tense and voice. You can search for them by appending _INF to an ngram. For instance, searching "book_INF a hotel" will display results for "book", "booked", "books", and "booking": Right clicking any inflection collapses all forms into their sum. Note that the Ngram Viewer only supports one _INF keyword per query. Case insensitive search. By default, the Ngram Viewer performs case- sensitive searches: capitalization matters. You can perform a case- insensitive search by selecting the "case- insensitive" checkbox to the right of the query box. The Ngram Viewer will then display the yearwise sum of the most common case- insensitive variants. Here are two case- insensitive ngrams, "Fitzgerald" and "Dupont": Right clicking any yearwise sum results in an expansion into the most common case- insensitive variants. For example, a right click on "Dupont (All)" results in the following four variants: "Du. Pont", "Dupont", "du. Pont" and "DUPONT". Warning: You can't freely mix wildcard searches, inflections and case- insensitive searches for one particular ngram. However, you can search with either of these features for separate ngrams in a query: "book_INF a hotel, book * hotel" is fine, but "book_INF * hotel" is not. Part- of- speech Tags. Consider the word tackle, which can be a verb ("tackle the. You can distinguish between. VERB. or _NOUN: The full list of tags is as follows: _NOUN_These tags can either stand alone (_PRON_)or can be appended to a word (she_PRON)_VERB__ADJ_adjective_ADV_adverb_PRON_pronoun_DET_determiner or article_ADP_an adposition: either a preposition or a postposition_NUM_numeral_CONJ_conjunction_PRT_particle_ROOT_root of the parse tree. These tags must stand alone (e. START_)_START_start of a sentence_END_end of a sentence. Since the part- of- speech tags needn't attach to particular words. DET tag to search for read a book. If you wanted to know what the most common determiners in this context are, you could combine wildcards and part- of- speech tags to read *_DETbook: To get all the different inflections of the word book which have been followed by. NOUN in the corpus you can issue the query book_INF _NOUN_: Most frequent part- of- speech tags for a word can be retrieved with the wildcard functionality. Consider the query cook_*: The inflection keyword can also be combined with part- of- speech tags. For example, consider the query cook_INF, cook_VERB_INF below. The Ngram Viewer tags sentence boundaries, allowing you to identify ngrams at starts and ends of sentences with the START and END tags: Sometimes it helps to think about words in terms of dependencies. Let's say you want to know how. That is, you want to. For that, the Ngram Viewer provides dependency relations with. Every parsed sentence has a _ROOT_. Unlike other. tags, _ROOT_ doesn't stand for a particular word or position. It's the root of the parse tree constructed by. So here's how to identify. The above graph would include the sentence Larry will. Larry said that he will decide. Dependencies can be combined with wildcards. For example, consider the query drink=> *_NOUN below. Pure" part- of- speech tags can be mixed freely with regular words. ADJ_ toast or _DET_. ADJ_ toast), but not with 4- or 5- grams. Ngram Compositions. The Ngram Viewer provides five operators that you can use to combine. Because users often want to search for hyphenated phrases, put spaces on either side of the - sign./ divides the expression on the left by the expression on the right, which is useful for isolating the behavior of an ngram with respect to another.* multiplies the expression on the left by the number on the right, making it easier to compare ngrams of very different frequencies. Be sure to enclose the entire ngram in parentheses so that * isn't interpreted as a wildcard.): applies the ngram on the left to the corpus on the right, allowing you to compare ngrams across different corpora. The Ngram Viewer will try to guess whether to apply these. You can use parentheses to force them on, and square. Example: and/or will. And well- meaning will search for the. To demonstrate the + operator, here's how you might find the sum of of game, sport, and play: When determining whether people wrote more about choices over the. Ngram subtraction gives you an easy way to compare one set of ngrams to another: Here's how you might combine + and / to show how the word applesauce has blossomed at the expense of apple sauce: The * operator is useful when you want to compare ngrams of widely varying frequencies, like violin and the more esoteric theremin. The : corpus selection operator lets you compare ngrams in. American versus British English (or fiction). Here's chat in English versus the same unigram in French: When we generated the original Ngram Viewer corpora in 2. OCR wasn't as good as it is today. This was especially obvious in.

Perhaps for one of these reasons: The Ngram Viewer is case- sensitive. Try capitalizing your query or check the "case- insensitive". You're searching in an unexpected corpus. For instance, Frankenstein doesn't appear in Russian books, so if you search in the Russian corpus you'll see a flatline. You can choose the corpus via the dropdown menu below the search box, or through the corpus selection operator, e. Frankenstein: eng_2. Your phrase has a comma, plus sign, hyphen, asterisk, colon. Those have special meanings to the Ngram.
