title: Coordinating knowledge to improve optical music recognition

authors: McPherson, John

abstract: Optical Music Recognition (OMR) is the process of automatically processing and understanding an image of a music score. This process involves various distinct phases to transform the image into primitive shapes, musical objects, and ultimately into a syntactic model representing the music's semantics. In general, OMR systems have performed these tasks in a linear sequence, so that the output of one component is the input to the next. However, this means that processing errors that occur in one of the tasks propagate through the system, and often when the error is eventually detected it is too late to reconsider the decisions leading to the incorrect classification or information. 
This thesis describes how OMR can be improved by modifying the recognition process from a sequence of linear tasks to a collection of modules that coordinate the information extracted from the data. Methods for_ data representation and controlling the system's flow of execution are investigated, and a practical implementation of such a system is described. This system has a message-passing design for providing contextual information from one module to another, such as suggesting possible classifications for an object. These messages are used to aid decision-making and to correct faulty decisions. This helps the system to adapt to a particular score while processing the image, increasing accuracy. 
This system is designed to aid in the research and evaluation of algorithms to achieve the above aims; therefore it is straightforward to modify various aspects of the system's behaviour, such as adding support for different music symbols. Examining the implemented system's behaviour clearly shows that this coordinated approach can correct many errors and can even identify some objects by only using syntactic information, based on the surrounding objects.

title: Song and Territorial Behaviour of Male-Male and Male-Female Pairs of the North Island Kokako (Callaeas cinerea wilsoni)

authors: McLeod, Jeffrey G.

abstract: Male-male pairing has been previously described for captive individuals of two duetting passerines. The sexually monomorphic North Island kokako (Callaeas cinerea wilsoni) is an endangered forest bird which is declining on the mainland of New Zealand, and is the only duetting species for which male-male pairing is known to be common in wild populations. This thesis determined whether male-male kokako pairs can be distinguished from male/female pairs on the basis of song and territorial behaviour. The first study began with a detailed analysis of the contributions that male/female pair members make to duets (n=11 pairs), with a focus on their use of fundamental frequencies and the proportion of the duet that was sung by each sex. Whole male/female songs were also examined in terms of the combined fundamental frequencies used by the pair as a unit (n=16 pairs). Females typically sang less in the duet than males (8 of 11 pairs) and they had a higher song pitch than males (5 of 5 dialects examined). However, some females sang much more than others and they sang at male-typical song pitches. The duet analysis led me to predict that male-male pairs divide the duet more equally and sing less at female-dominated song pitches than male/females pairs. The predictions were then tested on confirmed (n=3) and suspected (n=6) male-male pairs. One confirmed male-male pair only met the first prediction, while one confirmed and four suspected male-male pairs only met the second prediction. One suspected male-male pair met both, and the remaining two male-male pairs ( one confirmed, one suspected) met neither of the predictions. These results are discussed in terms of being able to identify male-male pairs, and in terms of the adaptive significance of male-male pairing. Male-male pairs may be identified using the predictions, however some male/female pairs might also meet the predictions in some dialects which could limit the reliability of this as a sexing technique. The second study examined the territorial responses of male-male pairs (n=6) and male/female pairs (n=7) to determine whether kokako pairs can 'range' song and to identify other ways of distinguishing between these pair types. Pairs were presented with their own songs in an un-degraded and a degraded form, and data were recorded on intra-pair spacing, song matching, song output, and the pair's movements in relation to the speaker. Kokako showed no differences in their response to the two treatments, nor did male-male pairs respond differently to male/female pairs. These results were attributed to an insufficient sample size, and the fact that the birds were able to have close-range experience with the speaker during playback which could have provided all pairs with obvious cues to locating the source of the sound. From the outcome of the first study, I recommended that the use of the predictions be confined to non-breeding kokako pairs because of the risk of encountering females that sing male-dominated song, and that the stability of kokako song features be assessed to determine whether patterns which currently distinguish male-male from male-female pairs in a population can be applied in the long term. From the outcome of the second study, I recommended that kokako song studies should first focus on obtaining an understanding of the structure of song and of the use of individual song elements, before further playback experiments are attempted. Recommendations with regard to the use of playback in population surveying were also given, with particular regard to ensuring that the source song is coherent to the birds.

title: Ngā kīrehu o Te Arawa ki Rotorua

authors: Morrison, Scott Jeffrey Tipene

subjects: Te reo Māori

abstract: Ko te reo Māori he reo tuauriuri whāioio, ā, he reo i kōhure ake i te whenua e kīa nei ko Aotearoa. Heoi anō, ka tae mai te Pākehā ki konei noho ai, ā, ka whārikihia ko ā rātou ture hei tauira tikanga mō ngā tāngata ki Aotearoa, ā, ko tō rātou reo hei reo whakaata whakaaro hei reo hoko parāoa hoki. I roto i ngā tau maha kua pahemo i raro i ēnei whakarite hou, kua memeha noa te reo Māori. Te mutu, i roto i ngā whakaakoranga hou i mahue ngā ahureitanga ake o te reo hei kawenga i te hihiri o te hinengaro Māori. Koinei ka tahuri ake au ki te whai i tētahi o ngā āhuatanga whakahirahira o te reo e mahue ana i roto i ngā akoranga i te reo hei reo tuarua.
Ko ngā kīrehu tētahi pekanga o te reo Māori kei te kaha te ngaro i te nuinga o ngā kaikōrero o te reo Māori o ēnei rā. Ki te waiho ērā momo kōrero kia moe, e kore e whakaara ake, ā, ko tōna mutunga, kua ngaro mō ake tonu atu. Kātahi tātou te ao Māori ka tangi mō tēnei āhuatanga nui o te reo ka ngaro i a tātou, ā, ko te rere a te ua koia anō kei te wai e riringi tonu nei te utu. Heoi anō, ki te mataara tātou, ki te whakaara ake i ēnei momo kōrero, ka whai kupu te reo Māori, ā, ka hoki mai te reo tuauriuri whāioio ki a tātou o tēnei reanga. Kei roto i ngā kīrehu e pupuri ana te wairua me te hinengaro Māori o ngā tūpuna o mua, arā, ka kite i te āhua o te whakaaro i roto i a rātou.
Ka tahuri ake au ki te whai i tēnei kaupapa kia whakaara ake anō ngā kīrehu kua roa e moe ana, ā, ki te kimi whakautu mō ētahi pātai i toko ake i te wā e whakaarohia ana te kaupapa nei. Tuatahi, i whakawhāiti taku titiro ki ngā kīrehu ake o Te Arawa waka e noho ana ki te rohe o Rotorua-nui-a-Kahumatamomoe. I pērā ai te whānui o taku titiro kia kore ai au e pokea e te kaupapa nei ka tahi, kia whakaara ake anō ai ngā kīrehu tūturu o tērā rohe kua tino roa nei e ngaro ana ka rua, ā, kia whakahoki mai ai ko aua kīrehu hei mahi mā tēnei reanga kōrero Māori kia ea ai te kōrero, "Ko Te Arawa māngai nui" ka toru. Tuarua, i whakawhānui ake taku titiro ki ngā kīrehu kei te mōhiotia e te motu.
Hei whakatutuki i taku kaupapa ka tirohia, ka wānangahia te kaupapa i raro i ngā upoko e whai ake nei. Kei te upoko tuatahi he whakamārama he aha au i whai ai i taku kaupapa mō ngā kīrehu. Kei te upoko tuarua he āta whakamārama i te kīrehu me ōna tikanga katoa, me ngā rerekētanga i waenganui i te kīrehu me ana hoa me te kīwaha, te huahuatau, te kupu whakarite, me te whakataukī. Ka titiro hoki ki ngā wāhi ka rangona, ka whakamahia rānei te kīrehu. Kei te upoko tuatoru ka tirohia ngā kīrehu kua kitea. E rua ngā wāhanga o tēnei upoko. Kei te wāhanga tuatahi ko ngā kīrehu o Te Arawa ki Rotorua me ā rātou whakamārama, kei te wāhanga tuarua ko ngā kīrehu o te motu whānui kua whakaraupapahia i raro anō i ngā upoko e whakaatu ana i te tikanga o ia kīrehu, me ā rātou whakamārama. Kei te whakamutunga ko te whakarārangi me te tūhonohono ake i ngā kitenga katoa i roto i aku rangahau, i aku wherawheratanga i te kaupapa nei me ngā hua ka puta ki te whāia ngā kīrehu i roto i ngā akoranga ki te hunga kātahi anō ka tahuri mai ki te whai i te reo Māori hei reo tuarua.
Kei konei ka whai wāhi ki te whakamārama i te huarahi i whāia e tutuki ai te kaupapa o tēnei mahi rangahau. I te wā e whakaarohia ana te kaupapa nei ka puta te whakaaro ki roto i a au kia kōrero tahi me ngā koroheke nō roto o Te Arawa waka, kia pātaihia rātou ki ō rātou mōhiotanga e pā ana ki tēnei kaupapa, me ngā kīrehu e mōhio ana rātou, kei te whakamahia rānei e rātou. Ka mutu, kia kōrero hoki ki ngā tāngata wetewete reo, ki ngā tāngata matatau, ki te rangatahi, me ngā koroheke o ngā iwi i waho atu o Te Arawa. Ehara i te mea he aha, heoi anō ki a au kāore kē he huarahi i tua atu i te kōrerorero-ā-tangata hei awhi i te rangahau o tēnei kaupapa. I pēnā ai te whakaaro nā te mea, ki a au ko te kīrehu he mea ka rangona i roto i ngā kōrerorero a te tangata, ā, he mea kāore e tino tuhituhi ana. Nā reira, i āta whakaaro au ko ngā wāhi kōrerorero noa a te tangata pea, ngā wāhi pai kia rapu mai i ēnei tūmomo kōrero. Nā, i whāia tēnei huarahi e au, ā, i tino whai hua tēnei o ngā huarahi. I kitea, i rangona ētahi kōrero whakamārama me ētahi o ngā kīrehu o Te Arawa i konei. Tāpiri atu ki tēnā, i rangona ngā whakaaro me ngā kōrero a ngā momo tāngata katoa, rangatahi mai, koroheke mai.
I tua atu i te kōrero tahi, arā anō ngā huarahi i whāia. I pūhia au e ngā hau kōhengihengi a Tāwhirimātea kia tae atu ki ngā tōpito katoa o Te Ika Roa a Māui; ki ngā whare pukapuka i Tāmaki, i Te Whanganui a Tara, i Kirikiriroa, i Pāmutana, i Rotorua. Hei aha? Hei āta rangahau i ngā kōrero e pā ana ki tēnei kaupapa. I reira i kitea ngā rīpoata tawhito me ngā rīpoata hou, ngā kohinga kōrero o namata, o nāianei hoki, me ngā reta i tuhia e ngā rangatira i tērā rautau, me ngā rārangi pukapuka e pupuri ana ngā kōrero o mua. I haere au ki Te Kōti Whenua Māori i Rotorua ki te pānui ngā kōrero e whakaatu ana i te noho a te Māori i ngā rā o nehe, me ngā kōrero i whakatakotohia e rātou ki mua i te aroaro o te kōti. I roto i ēnei tuhinga e mau ana ētahi kīrehu i whakahua ake i te wā i hui ai ngā tūpuna mō te whenua te kaupapa. Kei aua wāhi nui anō, arā, kei Tāmaki me Te Whanga Nui a Tara, e puritia ana ētahi tēpa kei runga nei ngā kōrero a ngā rangatira kua whetūrangitia. I tonoa kia whakarongo pīkari aku taringa ki ēnei tēpa, ā, i puta mai ētahi kīrehu i aua tēpa rā.
Nā ēnei momo huarahi i taea ai te whakaemi me te whakakao i ngā whakaaro me ngā kōrero katoa o tēnei tuhinga, ā, te putanga atu, kua whakarārangihia ngā kōrero, ngā whakaaro me ngā kīrehu i kitea mai, i rangona mai, i puta mai. 
Heoi anō, kāore te wai i marino i ngā wā katoa. I ētahi wā ka tae mai he raruraru, he uauatanga hei whakapakeke i te ara, he ngārara rānei hei whakapae i te huarahi. Ka pōuri te manawa nā te mea kāore au i whai wāhi ki te kōrero ki a Irirangi Tiakiawa rāua ko Tāmati Wharehuia i mua i tō rāua wehenga. I te whakatikatika au i a au anō ki te kōrero ki a Irirangi kātahi ia ka mate. Ka whakatika anō au ki te kōrero ki a Tāmati, ā, ka mate hoki tērā. Kāore e kore he kōrero, he mōhiotanga ā rāua hei whakamōmona i te tuhinga nei, engari e taea te pēhea? Ko tēnei mea te mate e kore e taea te karo, engari, i runga i tēnā āhua, kei te tangi tonu te mapu, kei te pōuri tonu te manawa.
I tua atu i tēnā, ka raruraru au i te korenga ōku e tino kite ngā kīrehu i roto i ngā tuhinga a te tangata. E tika ana te whakaaro, kāore ngā kīrehu e tino tuhituhi ana. I kitea ētahi i roto i ngā tuhinga, engari me uaua ka kitea mai ērā. E hia kē ngā hāora i whakapaua e au kia rapua mai ngā kīrehu e huna ana i roto i ngā pukapuka, i ngā reta, otirā i ngā momo tuhinga katoa a te tangata.
Ahakoa ēnei, he nui ngā painga i puta mai ki a au i roto i tēnei mahi rangahau. Ka mīharo katoa te kōrero tahi me ngā koroheke, i reira i āta rangona te reo o ngā mata o te ao kōhatu, me kī, te reo tuauriuri whāioio. I puta mai i a rātou ngā whakaaro tūturu o te hinengaro Māori tūturu hei awhi i te hanga o tēnei mahi rangahau. I pai anō rā taku haere ki te Whare Pukapuka o Turnbull i reira e pupuri ana ngā kōrero me ngā whakaahua a tua whakarere. I ētahi wā, nā te nui o ngā momo tuhinga Māori ātaahua i roto i taua whare pukapuka, ka titi taku haere ki kaupapa kē. Ahakoa i reira au mō te wiki kotahi, kāore rawa i oti i a au ngā tuhinga i hiahia au ki te pānui. Ko tētahi atu mea pai i puta mai ki a au i roto i tēnei mahi rangahau, ko te akoako i ētahi kīrehu, i ētahi kīwaha me ētahi whakataukī hou hei whakamahi māku i ngā wā e kōrero Māori ana au, me te whēkite o ētahi tuhinga Māori kāore anō au kia kite noa.
Heoi anō hei whakakapi i tēnei wāhanga, i hangaia mai tēnei pūtoi kīrehu hei whakaara ake i ngā kīrehu o Te Arawa ki Rotorua ka tahi, hei hua mā te hunga e ako ana i te reo Māori hei reo tuarua kia whai kupu tō rātou reo ka rua, hei whakahoki i ngā pātai i toko ake ai i te wā e whakaaroarohia ana tēnei kaupapa ka toru. Ināianei ka riro mā ngā kōrero, mā ngā tuhinga me ngā whakaaro kei te whai mai e whakatinana te kaupapa o tēnei mahi rangahau.

E hia kē ngā hāora i whakapaua e au kia rapua mai ngā kīrehu e huna ana i roto i ngā pukapuka, i ngā reta, otirā i ngā momo tuhinga katoa a te tangata.
Ahakoa ēnei, he nui ngā painga i puta mai ki a au i roto i tēnei mahi rangahau. Ka mīharo katoa te kōrero tahi me ngā koroheke, i reira i āta rangona te reo o ngā mata o te ao kōhatu, me kī, te reo tuauriuri whāioio. I puta mai i a rātou ngā whakaaro tūturu o te hinengaro Māori tūturu hei awhi i te hanga o tēnei mahi rangahau. I pai anō rā taku haere ki te Whare Pukapuka o Turnbull i reira e pupuri ana ngā kōrero me ngā whakaahua a tua whakarere. I ētahi wā, nā te nui o ngā momo tuhinga Māori ātaahua i roto i taua whare pukapuka, ka titi taku haere ki kaupapa kē. Ahakoa i reira au mō te wiki kotahi, kāore rawa i oti i a au ngā tuhinga i hiahia au ki te pānui. Ko tētahi atu mea pai i puta mai ki a au i roto i tēnei mahi rangahau, ko te akoako i ētahi kīrehu, i ētahi kīwaha me ētahi whakataukī hou hei whakamahi māku i ngā wā e kōrero Māori ana au, me te whēkite o ētahi tuhinga Māori kāore anō au kia kite noa.
Heoi anō hei whakakapi i tēnei wāhanga, i hangaia mai tēnei pūtoi kīrehu hei whakaara ake i ngā kīrehu o Te Arawa ki Rotorua ka tahi, hei hua mā te hunga e ako ana i te reo Māori hei reo tuarua kia whai kupu tō rātou reo ka rua, hei whakahoki i ngā pātai i toko ake ai i te wā e whakaaroarohia ana tēnei kaupapa ka toru. Ināianei ka riro mā ngā kōrero, mā ngā tuhinga me ngā whakaaro kei te whai mai e whakatinana te kaupapa o tēnei mahi rangahau.
