    <p>Let's begin with the question final purpose: my aim is to build a word-based neural network which should take a basic sentence and select for each individual word the meaning it is supposed to yield in the sentence itself. It is then going to learn something about the language (for example the possible correlation between two given words, what is the probability to find both in a single sentence and so on) and at the final stage (after the learning phase) try to build some very simple sentences of its own according to some input.</p> <p>In order to do this I need some kind of database representing a vocabulary of a given language from which I could extract some information such as word list, definitions, synonyms et cetera. The database should be structured in a way such that I can build C data structures containing the needed information such as </p> <pre><code>typedef struct _dictEntry DictionaryEntry; typedef struct _dict Dictionary; struct _dictEntry { const char *word; // Word string const char **definitions; // Array of definition strings DictionaryEntry **synonyms; // Array of pointers to synonym words Dictionary *dictionary; // Pointer to parent dictionary }; struct _dict { const char *language; // Language identification string int count; // Number of elements in the dictionary float **correlations; // Correlation matrix between i-th and j-th entries DictionaryEntry *entries; // Array of dictionary entries }; </code></pre> <p>or equivalent Obj-C objects.</p> <p>I know (from <a href="https://stackoverflow.com/questions/1696387/searching-the-mac-osx-system-dictionaries">Searching the Mac OSX system dictionaries?</a>) that apple provided dictionaries are licensed so I cannot use them to create my data structures. Basically what I want to do is the following: given an arbitrary word A I want to fetch all the dictionary entries which have a definition containing A and select such definition only. I will then implement some kind of intersection procedure to select the most appropriate definition and synonyms based on the rest of the sentence and build a correlation matrix.</p> <p>Let me give a little example: let us suppose I type a sentence containing "play"; I want to fetch all the entries (such as "game", "instrument", "actor", etc.) the word "play" can be correlated to and for each of them select the corresponding definition (I don't want for example to extract the "instrument" definition which corresponds to the "tool" meaning since you cannot "play a tool"). I will then select the most appropriate of these definitions looking at the rest of the sentence: if it contains also the word "actor" then I will assign to "play" the meaning "drama" or another suitable definition. The most basic way to do this is scanning every definition in the dictionary searching for the word "play" so I will need to access all definitions without restrictions and as I understand this cannot be done using the dictionaries located under /Library/Dictionaries. Sadly this work MUST be done offline.</p> <p>Is there any available resource I can download which allows me to get my hands on all the definitions and fetch my info? Currently I'm not interested in any particular file format (could be a database or an xml or anything else) but it must be something I can decompose and put in a data structure. I tried to google it but, whatever the keywords I use, if I include the word "vocabulary" or "dictionary" I (pretty obviously) only get pages about the other words definitions on some online dictionary site! I guess this is not the best thing to search for...</p> <p>I hope the question is clear... If it is not I'll try to explain it in a different way! Anyway, thanks in advance to all of you for any helpful information.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
