<p class="MsoNormal">could be viewed as indicating a number of simultaneous constraints with regard to a desired sentence. With an expression tree model, we could form expressions for a constraint-based system while making use of objects in scope.</p>

<b>Subject: </b>RE: Conjugation and Declension Functions</p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<div>
<p class="MsoNoSpacing">Thank you all for the comments and feedback thus far.</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">I would like to indicate that we could also utilize the expressiveness of JavaScript/TypeScript for array literals with object literal elements. In this alternative approach, arguments could be placed into an array of objects which each
attach a thematic role to an argument. “Bobby”, “ball” and “bat” could be objects of type Noun, and we could pass to a function an array literal of object literals to get at the desired concepts of: (1) sequence, (2) roles, (3) values. That is rather the matter:
attaching thematic roles to elements of a sequence of arguments.</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">To the example pseudocode:</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">Noun Bobby;</p>
<p class="MsoNoSpacing">Noun ball;</p>
<p class="MsoNoSpacing">Noun bat;</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, [ {role: ‘agent’, value: Bobby}, {role: ‘patient’, value: ball}, {role: ‘instrument’, value: bat} ]) --> “Bobby hit the ball with the bat”</p>
<p class="MsoNoSpacing">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, [ {role: ‘agent’, value: Bobby}, {role: ‘instrument’, value: bat}, {role: ‘patient’, value: ball} ]) --> “Bobby, with the bat, hit the ball”</p>
<p class="MsoNoSpacing">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, [ {role: ‘instrument’, value: bat}, {role: ‘agent’, value: Bobby}, {role: ‘patient’, value: ball} ]) --> “With the bat, Bobby hit the ball”</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">or, if the grammatical arguments (voice, tense, aspect, mood) are properties of the context object:</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
</div>
<p class="MsoNoSpacing">hit(context, [ {role: ‘agent’, value: Bobby}, {role: ‘patient’, value: ball}, {role: ‘instrument’, value: bat} ]) --> “Bobby hit the ball with the bat”</p>
<p class="MsoNoSpacing">hit(context, [ {role: ‘agent’, value: Bobby}, {role: ‘instrument’, value: bat}, {role: ‘patient’, value: ball} ]) --> “Bobby, with the bat, hit the ball”</p>
<p class="MsoNoSpacing">hit(context, [ {role: ‘instrument’, value: bat}, {role: ‘agent’, value: Bobby}, {role: ‘patient’, value: ball} ]) --> “With the bat, Bobby hit the ball”</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">A downside would be that the function signatures would resemble:</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">hit<…>(Context, Array)</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">or</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">hit<…>(Context, Array<RoleNounPair>)</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">An upside would be expressiveness with which to indicate desired output paraphrases.</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">These topics are discussed in <i>Building Natural Language Generation Systems</i> by Reiter and Dale [1], in chapter 6 on
<i>Surface Realization, </i>in section 6.8 on <i>Bidirectional Grammars</i>, pages 194 – 195, where the authors indicate that while “a parser might produce the same logical form for the following three sentences:</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<ol style="margin-top:0in" start="1" type="a">
<li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l1 level1 lfo2">Mary gave John a ball.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l1 level1 lfo2">Mary gave a ball to John.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l1 level1 lfo2">John was given a ball by Mary.<o:p></o:p></li></ol>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">“The input to a realizer, however, should explicitly provide a means of choosing among these forms; the alternative is to choose at random.” (as noted, another alternative is to select using a manual of style).</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">The authors also indicate that Winograd [2] provided a list of paraphrases for consideration:</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<ol style="margin-top:0in" start="1" type="a">
<li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">Jon bought a painting for Vina.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">Jon bought Vina a painting.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">Vina was bought a painting by Jon.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">What Jon bought Vina was a painting.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">What Vina was bought by Jon was a painting.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">It was a painting that Jon bought for Vina.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">It was Jon that bought Vina a painting.<o:p></o:p></li><li class="MsoNoSpacing" style="margin-left:.25in;mso-list:l0 level1 lfo3">It was Vina that Jon bought a painting for.<o:p></o:p></li></ol>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">On the topic of “a” or “the”, definite or indefinite noun phrases, we can note a discussion in Reiter and Dale [1], section 5.4.2, on page 145. That is another important discussion topic.</p>
<p class="MsoNoSpacing"><o:p> </o:p></p>
<p class="MsoNoSpacing">In the set of approaches under discussion, by making use of grammatical arguments (e.g. voice, tense, aspect, mood) and by placing thematic roles on elements of a sequence of arguments, we have an expressiveness beyond that of predicate
calculus with which to distinguish paraphrases.</p>

</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In addition to broaching the discovery, encoding and reuse of language-specific patterns, which I view as a discussion topic when comparing and contrasting approaches (see: the DRY principle [1] and the abstraction principle [2]), and indicating
how conjugation and declension functions would facilitate the discovery, encoding and reuse of these patterns, I would like to share some topics which arose as I explored adding the thematic relation [3] of instrument to the agent-patient pair.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When exploring how best to add the thematic relation of instrument to the agent-patient pair (e.g. adding “using the bat” to “Bobby hit the ball”), I observed that, for the same input grammatical arguments, there was a set of possible output
paraphrases:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l2 level1 lfo4">“Bobby hit the ball using the bat”<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l2 level1 lfo4">“Bobby, using the bat, hit the ball”<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l2 level1 lfo4">“Using the bat, Bobby hit the ball”<o:p></o:p></li></ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I wondered: how might we be able to generate each?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One possibility is indicated. There could be a type for each thematic relation [3]. Then, using explicit type conversions to these types, we could have different functions for different sequences of input arguments.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">That is,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, (Agent)Bobby, (Patient)ball, (Instrument)bat) --> “Bobby hit the ball using the bat”<o:p></o:p></p>
<p class="MsoNormal">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, (Agent)Bobby, (Instrument)bat, (Patient)ball) --> “Bobby, using the bat, hit the ball”<o:p></o:p></p>
<p class="MsoNormal">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, (Instrument)bat, (Agent)Bobby, (Patient)ball) --> “Using the bat, Bobby hit the ball”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">or<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, Bobby as Agent, ball as Patient, bat as Instrument) --> “Bobby hit the ball using the bat”<o:p></o:p></p>
<p class="MsoNormal">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, Bobby as Agent, bat as Instrument, ball as Patient) --> “Bobby, using the bat, hit the ball”<o:p></o:p></p>
<p class="MsoNormal">hit<voice::active, tense::past, aspect::perfective, mood::indicative>(context, bat as Instrument, Bobby as Agent, ball as Patient) --> “Using the bat, Bobby hit the ball”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">These functions could each wrap the use of patterns (as indicated in previous email) and attempt to realize output sentences utilizing the arguments in the same sequence in which they were provided. This would, however, mean that the callers
of the functions would be responsible for “shuffling” the input arguments to express the desired paraphrase ((1), (2), (3)).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There are, of course, other approaches to consider and other possibilities to consider with respect to addressing the matter of outputting the example paraphrases.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any thoughts on these topics?<o:p></o:p></p>

<p class="MsoNormal">For English, there might be more generic parameters than those for voice and tense; we could add those for aspect and mood (e.g.
<span style="font-size:10.0pt;font-family:"Courier New"">pattern1234<V, T, A, M>(…)</span>).<o:p></o:p></p>

<p class="MsoNormal">In conclusion, with generic programming and functions for conjugation and declension, we have expressiveness with which to discover, encode and reuse language-specific patterns.<o:p></o:p></p>
